The only way to scare the opposing team into not feeding of your retarded AI is to give the gold earned by killing the AI not to the persone who killed it, but to it's team. Some may not prefer it which is why you should really have an option in the lobby like:
When a player disconnects:
-exit the game without recording it
-concede the game
-give gold earned by killing to the opposing team (my ideea)
-continue with AI
-continue but with the AI stuck near the health crystal (so no feeding will occur)
-etc
