Google were processing JavaScript for crawling websites more than a decade ago (a quick search suggests since ~2008).

It's not GPT that's having the issue it's what's feeding GPT the website.

Is there any literature out there on how they do it at large scale?

From my understanding it’s tough and expensive ( selenium and rotating resedential ips) am I misinformed?

Google doesn't need residential IPs, since websites tend to treat Googlebot specially

Google purposefully obfuscate the details, AFAICT. I've not done SEO for ~5 years, I'm not sure I know anything useful on the subject any more.
