By and large, no. That's not to say that those sites are not generated programmatically--without a doubt, most of them are--but not by a cutting edge transformer model. The fact is, generating words has never been the bottleneck for blackhat SEO types. Generally, those sites are generating their content through some kind of scraping, or in rarer cases, paying pennies for nonsense articles. The page itself is structured for search (targeted H1s, metadata, etc.) and some kind of private blog network is used to create a pyramid of backlinks.
