How to change auto attack binding.

LoL has without doubt the worst controls I've ever seen in a game, and I was just looking for a way to rotate my map so I can play without dodging all the red side games, but I can't find anything so I'm moving onto my other big issue with this games controls.

Auto Attack and Movement are the same button, I've played since season 3 trying to get over the same two issues so that I might have some hope of playing this game for real, and it's season 7 and I'm no better at dealing with them then I was in season 3.

Is it possible to rebind either of my mouse functions to the left mouse button? Right now my left mouse button goes completely unused, it would be so nice to auto attack with it that way when I try to auto attack as a ranged champion I don't walk up into melee range before doing it.
