I never got that impression while playing with the mod in DOS2. Battles felt like a party effort and I still got to put in work, it didn't feel like the AI were carrying me through the game, but then again I also modded my game to be extremely difficult. I guess the benefit of having Larian implement this instead of it being added by a mod is that Larian can make sure party AI are intelligent but not to the point they know how to essentially insta kill the enemy. When I played DOS2 with AI controlled parties we still got completely wiped on occasion, but it was never just a breeze when we did win. I've never tried it with base game difficulty though.
