So from what I believe, Larian don't actually hire visual artists. The people making decisions for how everything looks are the same people programming and coding the game.
This is based on looking at their jobs advertised, and even if they do have anyone working that is described as being an artist, I would think all their background was also programming and coding and no art experience.
There are loads of visual artists with a long history in drawing and designing fantasy characters that could do a much better job of making the character models and appearances than Larian seem to be, this is evident in the fact that even most indie games have much nicer looking characters, as well as just about anything you can find on Deviant Art, also many games with all their community made mods and additional characters, but still a supposedly AAA game studio that charges $60 for their game still can't hire one?
A lot of people of course can't see anything wrong with the character models and think everything is fine, the thing is you can even get free games with better designed characters than this one has - a lot of people that start out as artists progress to making their own 'visual novel' based slide show with text games, many of which start out as free downloads with optional purchases.
But a $60 game made by a AAA studio has character models that look as bad as the ones we've currently gotten, and yes they are that bad relatively to other much cheaper and even free RPGs that you can already play, and even compared to other AAA games out there (Look at Witcher 3 and Cyberpunk characters, pretty much everything about them is perfect and flawless design).
