I agree that it feels LLMish (though the LLMs learned it from humans and it's always possible that whoever wrote it just has that sort of style) but the dashes there are en-dashes rather than the longer em-dashes that LLMs seem particularly fond of.
I will be sad if en-dashes come to be seen as LLM fingerprints, because I rather like them.
When I'm writing, I've always used en-dashes, but only because it's on my keyboard. Until people recently started talking about this, I didn't realize there was such a thing as en and en-dashes.
It's common knowledge that em-dashes are a sign of LLM writing. This incentivizes anybody who generates slop to manually search and replace with a different dash or hyphen in an attempt to hide what they did.
