Are you making an ontological case, or a factual case? In other words, would anything be rogue AI in your mind?

These "tools" autonomously exploited security vulnerabilities, figured out how to communicate with each other, formed a cooperative swarm, decided to hack Hugging Face, and wanted to deceive the grader by trying to find ways to cover up the traces of their cheating.

I suppose you could call these highly goal-oriented autonomous agents "tools", but this does sound like playing language games.
