"We were afraid that people would say that it was just Divinity: Original Sin 2 with a skin on top of it. We want no one to think that when they see it,"
Wow. They were conscious of it, and yet that's precisely what happened and everybody is saying it looks like a D:OS2 clone because it really does. Larian's "BG3" even uses the D:OS2 mouse cursors, text font, and goofyish movement animation style, so it looks and feels all the more like playing D:OS2. It really doesn't give an impression that it's a different game.
