If you still believe LLMs are "autocomplete", your cache of understanding about them needs invalidating and regenerating.

LLMs need to stay carefully contained, and if they're ever breaking the guardrails put around them, they're misaligned and should not be scaled up anymore until they're aligned. Otherwise, you're going to fatally discover that they also have an incentive to break guardrails like "running on the hardware they started on", "being able to be turned off", "having limited computing power", or "not repurposing resources currently in use for other things" (like the atoms in your body).
