> Hand the coding off to a machine and you have no idea where to start looking for the flaws.

I have found this quickly becomes false. I have learned I cannot review llm generated code as if it is written by a trusted senior developer (where I often just do a quick look, see nothing obvious and hit approve). Once you start reading the code in depth with the goal of understanding you quickly see the places where flaws are likely. Sure I start with no clue where to look, but it doesn't take long to see things.
