I need a braindead ADC to play for whenever I have to autofill. Any suggestions?

I usually play really easy and dumb faceroll champions and pretty much everything I play is melee. It worked out for me so far but recently I started autofilling ADC instead of supp. No surprises, I started feeding incredibly hard and played horribly.

ADC is by far the hardest and most frustrating role to play and I'll likely never learn how to attack move because I'm too lazy for that. So I need something easy to rely on that I can play in the botlane without feeding.

So, is there any ADC that can do this? I feel like everyone of them is too hard no matter what. Might aswell get the most braindead one of them then, if I knew who that would be of course.

So who is it?
