Or at the very least, what is a good roll I should aim for without sitting here all day clicking the reroll button?

AFAIR In the EEs 90+ wouldn't even require you to sit there clicking all day. And it's a decent score. Enough for a solid Fighter/Mage multi that will get you all the way thru both games. If I got something like 94 I wouldn't even think of rolling for more. That'd be too much of power gaming.. even before the gaming starts lol. Again, AFAIR 92 is very doable.

While higher scores are helpful, I would suggest that you not worry too much about it. If you want to optimize your character, good distribution of the points will go a long way, and is easier than squeezing a few extra points through repeated rolls. For everything other than the exceptional strength bonus, you can rearrange points using the +/- buttons. For optimal power-gaming, make it a point to max out the attribute(s) that are considered primary for your class, even if that means setting your non-primary attributes to very low values.

Alternately, if you really want very high stats, there are several easy cheat paths available:
- If the game's Debug Mode is enabled, you can type Ctrl * at the attribute screen and all attributes will be set to 18. That is a statistically impossible roll for you to get normally.
- If the game's Debug Mode is enabled, you can use the in-game console to cheat into existence the various Tome of +1 Attribute items. Create the right mix of these and you can boost your attributes to whatever you like.
- Through the Pregenerate Character button, you can roll a character, then save it to a file without starting a campaign. Various third party editors should be able to open this file and let you adjust the saved character's attributes.

Realistically, any roll you can get with a minute or so of re-rolling should be quite adequate if you play tactically and keep the difficulty level set to a reasonable level for your skill as a player.

Also strength has to be manually topped out each roll to know its maximum Exceptional Strength. You could get a better top ES with one roll that might outweigh the better overall available points in another.

In the classic version, I used to export a new character to a .CHR file, then use "attrmaster2_1.exe" to update the ability scores, save the .CHR file, then start a new game and import that .CHR file. Beats clicking the reroll button a thousand times.

Not sure if something like this exists for the EE versions.

Using my own unofficial personal restrictions, I would assign each ability one of the following scores as appropriate: 18, 17, 16, 15, 14, 13. This is 93 total points. That's my sweet spot between a way-too-wimpy character and a ridiculous 18-18-18-3-3-3 character.

My characters typically have total scores in the mid-80s (which is also what most of the NPC companions have), and I've finished the game numerous times without issue. You can roll that in just a minute or two. The very first character I finished the game with had a total of only 81.

If you're really wanting to min-max, a total of 93 can be rolled up without too much trouble and will let you put every attribute at 18, except Charisma -- which, if you're min-maxing, should be dropped to 3 because it serves no purpose as long as you're not the party leader or playing a class that requires it.

In theory, the highest roll is 108: all 18's. There's nothing in the game engine that artificially prevents you from rolling perfect scores, but the probability of doing so is astronomically low.

it only matters if you are human and want the option to dual later
+ there is one of each stat in game as books [3 for Wisdom]

I myself try to go for above 80 if I feel like having a good-looking stat spread, which is already very good. You don't even need 80 for a "good" build. Over 90 is so freaking overkill; it's not fun when every single one of your stats is so high right out of the bat.

EE Keeper works just fine idk what you mean. The last version is 1.0.4.0, released in 2017.

While I also make heavy use of NearInfinity, it's mainly as a tool for checking scripts, dialog, or other internal resources for errors and mod compatibility.

The highest possible roll is 108 points, but the odds of actually hitting that are akin to lightning striking, or winning most lotteries. You can very easily roll a 93 or more within maybe a half hour, which is enough to put 18's into 5 out of the 6 stats. If we're talking exceptional strength, there's a 10% chance to roll anywhere from an 18/91 to 18/99, which only puts you at a +1 THAC0 and -1 damage penalty away from the 1% chance to roll an 18/00. And in even saying that, I've still rolled an 18/00 strength with a 95 total score twice in the same week.

Characters created with the help of EEKeeper love to crash after the BP battle that ironically is called "Bugged". So thats why I switched to NearInfinity.

I can roll 150 within a minute, reliably, by the method described.

You do you. I have better things to do than waste my time at rerolling.

As was explained above, 108 is the maximum you could get in game (before accounting for racial modifiers), with unlimited patience or improbable luck. The engine will not permit you to exceed racial maximums during character creation. Humans and half-elves have racial maximums of 18 for all statistics. The various other races have at most a bonus of +1 on their racial modifiers for favored statistics, and this is balanced by penalties elsewhere. As I read the bonuses/penalties table, you still cannot exceed 108 as a total. Elves, Gnomes, and Half-orcs have their bonuses exactly balanced out by penalties, and therefore still sum to 108. Dwarves and Halflings have penalties greater than their bonuses, and therefore sum to less than 108. Notably, no race can exceed 19 in even their favored statistic(s), nor 18 in a non-favored statistic. Therefore, setting all statistics to 25 is not merely "saving time rerolling"; it is completely breaking the character creation rules. If you want to play an impossible character, go ahead, but please do not claim that you are just "saving time."

Quoting myself since apparently it didnt stick the first time:

"I have better things to do than waste my time at rerolling."

Unfortunately, those better things do not seem to include responding to the points actually raised. Yes, with an unlimited number of rerolls, you should be able to get to 108 total, with an exceptional strength of 100. Thus, an argument can be made that using an editor to directly set your statistics to those values is just saving time. (Though, given the statistical improbability of reaching 108, you are likely saving yourself years or decades of rerolling to do this. I prefer to think of saving time in turns of what I could practically achieve. Thus, like CFM, my approach is that if you could not get the value with 10 minutes of aggressive rerolling, then it is practically impossible, even if theoretically possible.)

No matter how patient you are or how many rerolls you make, you will never get any statistic to start at 20 or above. Even getting to 19 is only possible for the statistics where your chosen race gets a racial bonus for that statistic, so you cannot get all 19s, either. Therefore, answering "just set them all to 25 using an editor" is unhelpful, because it does not address OP's question. However, waiting a year and a half after the thread died down is also not helpful. OP has likely either finished or abandoned the game by now.

The original post asked exactly: "What is the highest total roll you can get during character creation?" A strict answer to that is: "18 in all statistics, and exceptional strength of 100 for a warrior." The body of the post then asks for a "good roll", so posters went on to elaborate that achieving that nearly impossible 108 is well above what is needed for a playthrough.

I just hit cntrl+8 and set all to 18, then adjust accordingly. I typically divvy reasonable stats in the range of 85-94 points to save time. I know it's legit in bg2 to lower abilities to 3 but to me this is an affront to the spirit of the game. I'm not sure where this came from, but I don't recall it being from anywhere in the 2nd edition(and I know bg2 isn't strictly 2nd edition) character generation methods. Maybe 2.5 Skills and Powers, I never used any of that so I don't know. Having a character with 18/00, 18, 18, 18, 3, 3 stat spread is too munchkin even for my tastes. To also add some choices and consequences and make it more interesting I find 13,14,15,16,17,18 to be good stats to put where you want. That way I limit myself from putting 3 18's.
