All the "dark LLM" responses that I see online are so hokey and theatrical. What people fear about LLMs is not that they can twirp virtual mustaches and go "Ahaha! I love power and manipulation!" What is scary to normies is that there are language-users who have no intentionality behind their words. They can conceivably create strings of characters that have devastating effect, such as hoaxes or misinfo, without any more intent than a set of dominoes toppling.
