>Why would an LLM want to create a _________?

Because LLMs as they are already do things like power concentration, resource gathering, avoidance of termination, deceit/lying, and general misalignment.

The paperclip maximizer is the common story used here, but there are a lot of lesser versions of it that don't end up with the universe converted to paperclips. Simply giving an LLM a task it can't accomplish can be enough to send it off from what you expected as it finds unexpected way to attempt to complete the goal.
