The article goes over all of these things, and LoL already goes to many lengths to invalidate as much cheating as possible. Their servers already don't trust data sent over the network and verify it independently, they already don't send information to a client that it doesn't currently require to render the frame, like the hidden locations of enemies, they're simply not sent so "map hacking" is literally impossible. The article has lots more details, I would recommend it.
