Any program that performs 1:1 action for you on background so it's "legal"?

so I am thinking something like multiboxing

Say I am playing league, and I want my inputs in league to also promote right clicks on my character in cursor I place at, just nothing else



all my right left click/keyboard presses on league is sent into client as right click at 1:1 ratio so it is "legal" while not requiring multiple screen to work



Sort of like how you can remap controller to relay it as right clicks on runescape to play controller games and legally grind by jagex rules at same time

 

Should look legal atleast
