Personally, it’s Faith from Farcry 5 for me. Uninteresting dialog that can be summed up to “I was bullied once” and that’s it. Literally every other character is so much more interesting. Jacob gives you a sequence where you run through a gulag which he then uses against you, John tries to kill you and is openly hateful towards you plus is a character you get to interact with, and Joseph is a lunatic who was right.
There’s just so many characters whose entire presence makes me go “please shut the fuck up” that it’s hard to pick just one. Like yeah pretty much anybody would sell Preston Garvey to Satan for half a donut, but there are just so many other annoying characters…
