Script kiddies never did their shenanigans manually. And they were always perfectly capable of running their scripts in a while loop. A "robot" that you're describing is the same script in a loop, running on the same machine, but instead of running their scripts from a static file, it now runs it from the output of an LLM, and even though sometimes it yields some unexpected results, on average it's nothing new.
The difference is, a script that tries known exploits against a list of IP addresses and ports costs nothing. Same, but put through an LLM costs money, for worse "results".
