All that I see being "new" with LLM regurgitated garbage is that they call the system doing it an AI and not just a spam bot. Even back in the day, randomly entering words and adding ".com" to the end would result in either: a legitimate website, a porn site, a 404 error, or a page filled with random text like an AI generated article that wasn't hard to determine was made by a computer and not a real human either there to popup when searching literally any words and trying to generate traffic for ads, or as a placeholder for the domain name.

Now that it's harder to tell it's randomly generated vs human generated, even the "legitimate" websites are using it.
