Not really. To properly understand code you must have a mental model of what it is doing. You need that model whether you are reading or writing the code. It is easier to build that model while writing the code than while simply reading it. To build the model while reading the code requires having the same understanding of the problem and the same approach already in mind, which is almost never the case for any moderately complex problem.

Reading LLM generated code does not avoid this, and in fact it is often worse since LLM comments are terrible at getting to the point.
