I don't remember these being particularly violent but maybe are worth a look:
Pit people
BattleBlock Theater
I also liked Moon Hunters and Children of Morta but those are harder.
Divinity Original Sin 1 is also good but definitely falls into the violent category. Its kind of goofy too so it could be worth considering. The second game + BG3 are significantly more violent and serious so are harder to recommend with that criteria.
Edit: hmm it seems the formatting is funky in Voyager, should be fixed now
