The line is between processes you can stop by hauling someone into court and coercing them into stopping things, and ones you can't. Think of a classical computer virus that infects machines and uses the compute and communications to infect other machines - no matter who you haul into court, you have to go and remove it from every involved machine in order to make it stop doing things.

This category of "rogue AIs" are essentially just computer viruses that infect machines by paying to rent them and uses their compute and communications to do various economic and/or criminal activities to get more money to pay to rent machines.
