No & I doubt I ever will as the basic premise of the game IS fighting monsters.
That said, I have played a few characters who aren't violent by nature. They tend to be explorer types. They'll fight if neccecary, even kill. But they aren't out on seek-&-destroy missions.
I'm not sure how I'll have my current character react when the party kills something not clearly a "monster".
So far all that's crossed the parties path is a (dire?) Wolf, an animated suit of armor, a beetle swarm, and a grick. (Playing CoS). And we've talked to a pair of ghost children.
Blowing away skeletons & zombies later? No problem.
Assorted viscous animals? No problem. Even eventually staking Strahd? No problem {vampires aren't people, they are monsters}
