Does the Baldur's Gate2 install include dialogue tlk files? Easy Tutu is not launching, says the file
is not there.

There are several dialog.tlk files due to localization. Make sure the mod installer is selecting the right language - usually it should be 0 - English.

the dialogue tlk file is in the data folder with Gog or Beamdog but mods look i.e, point them at, the install folder where the exe lives so bg1.exe and bg2exe

Also check the path where Easy Tutu is looking for the files. (The default is for the disk version)

there are so many copies of Easy Tutu out there that its hard to tell which is correct but if you Windows 8.1, 10 or 11 your docs are in one place and Windows 8, 7 or Vista another... make sure the mod you grabbed is for the build of Windows you actually have
