This need not be an either/or case.

Some players like letting the dice influence the outcomes. It's the tabletop RPG experience. And importantly, it is the vision Larian wants to put forward.
But some players would like them gone or the DC of check greatly reduced, so they can call the shots.
Some players (that's me) will want to enjoy the game both ways.

The great thing about BG3 being a (mostly) solo video game and the Supreme Power Of Programming, is that Larian doesn't need exclude a part of the audience. They can simply include an option that says "trivialise all conversation skill checks", perhaps with a scale : you could move the DC of checks to x% of their current levels (with x between 0 and 200). It should come with a warning "this is not how we intended the game to be played", but that's all.
It's cheap to code. So I hope they'll do that.
