The option only affects melee by design, I think it says on the tooltip if you hover over it. I got tricked by that as well at first and confidently tried to non-lethally shoot a shopkeeper and ended up with a murder charge.Very mixed feelings about the game so far.
I've knocked out some peasants using the "switch to non-lethal" option, but the game seemed to have acted as if I killed them. I was honestly sure that the game wouldn't acknowledge it and was ready to stop playing, but it did in the end actually acknowledge the fact that I didn't kill them. I suppose I will continue playing on.
I've had some weirdness w/ this option related to ranged attacks especially. Spells? Forget it. No way to non-lethal a spell, ranged seems to sometimes kill them inadvertently. Only a melee strike when they are near 0 hit points seems to be reliable.
It does seem very half-implemented. I knocked the Drow raid leader out, which was tricky given the setup of the battle, and she's never been mentioned again thus far. I'm making sure to knock out basically every named character but so far there's been absolutely no reaction from anyone. And citizens never care if you knock them out, they just forget entirely by the next day.
