“Dark pattern” can apply to situations where the behavior is deceptive for the user, regardless of whether the deception itself is intentional, as long as the overall effect is intentional, or is at least tolerated despite being avoidable. The point, and the justified criticism, is that users are being deceived about the merit of their ideas, convictions, and qualities in a way that appears sytemic, even though the LLM in principle does know better.

I don't think this is the case.
