For BG2 / Tutu / Trilogy, you can use TobEx
mod to remove the cosmetic attack animations if they really bother you. I think it looks better without them myself.
(Note however TobEx is recommended to be first in the mod install order, before the Fixpack(s), so you might have to uninstall and reinstall mods. Also pick carefully which TobEx options you select, as some are very close to cheats / ruleset changes. After installation you can change options by editing the INI files to your liking without reinstalling).
