You don't learn new languages/paradigms/frameworks by inserting it into an existing project. LLMs are especially tricky because they do appear to work magic on a small greenfield, and the majority of people are doing clown-engineering. But I think some people are underestimating what can be done in larger projects if you do everything right (eg docs, tests, comments, tools) and take time to plan.
