>Typing the code myself forces me to slow down, which means I'm more likely to detect hallucinations or bad design choices the LLM might have made.

I think this depends on your level of expertise with the task.

If I'm writing a language I am extremely familiar with and so second nature to me, for example SQL then I can instantly read llm code.

But if a new language or a new piece of software then llm generating huge amounts of code can make it difficult to improve yourself and also manage the quality.
