It could be a gimmick to grab attention.

Lots of novels start off with "the gardener put down the gun" or "the elephant was never recovered" or "the money was meant to be in the shoebox" or something as a way of arousing the reader's curiosity, or making the reader feel like an active participant in some larger story that's already underway, even though this is technically bad pragmatics in the sense that it isn't cooperating with the reader's assumed desire to understand the context of the utterance.

In turn, perhaps some AI systems have learned this trick as a way of increasing engagement, even though it can feel manipulative.
