Two websites don't sound like insubstanial projects.

With LLMs you can make 20 websites and still not really understand the language. For learning you really do have to type the code out yourself. That's how you build familiarity and understanding. Reading code is a good starting point, but it doesn't really gel until you start writing your own ideas down, fail, and try again until it works and makes sense. Especially if you're working in a new language with unfamiliar semantics.
