Navigate to your config folder and open input (League of Legends/Config/input)
Add in the following lines of code:
[GameEvents]
evtPlayerMoveClick=[Button 1]
evtPlayerSelectClick=[Button 2]
If [GameEvents] already exists, just add the last two lines below it (That would be if you already have changed current keybindings inside of the game).
There you go.
Right click is now left click, and vice versa.
So for all of you who want to left click attack move and right click select items, have at it!
I wish I could have known about the view from halfway down
