I would encourage you to try Replit!

Deployment is literally a button. Granted, to a replit subdomain. But following some documentation to add your own domain is not out of reach.

You can do this with github pages too, including your own subdomain. ChatGPT could walk you through the steps but there is no requirement for an LLM.

There's been big efforts to simplify this stuff for years. Lots of good tooling out there (which the right questions to an LLM will yield for you).

I think LLMs help with stuff like deploying a website, but they aren't a requirement. You still need to know what you are doing if you want to do something complex.

Cloudflare pages is another option for simple static sites, it's easy to set it up in minutes just following ChatGPT response.

Though I feel this only works well for tech that are widely used.
