Taking a quick look at https://pspdfkit.com/api/documentation/tools-and-api/, I'm puzzled.... what distinguishes a "PDF Generator" from a "PDF Creator" from a "PDF Writer"? How would I know which one I want?

Oh, looks like they're the exact same thing: a webpage-to-PDF service.

Then there are a whole bunch of "PDF Converter" options, including "HTML > PDF", which seems to be yet another name for the same thing.

For me, all this has a whiff of SEO spam that I find quite distasteful. Just tell me what the product does. Don't try to list it under a collection of different titles in the hope of catching more search terms, it just makes you sound like a snake-oil salesman.
