I've thought that a lot of present LLM-speak is a distant descendant of the heyday of the "Now See This", Buzzfeed, et al clickbait that was en vogue about a decade or dozen years ago. A sort of chirpy contrarian provocation to drive reader engagement. "You won't believe how this X" begets "this isn't just Y -- it's Z." So it will be a style that eventually leaves as new models are trained on other writing.
