Then why have seasoned programmers accepted that getting an LLM to generate messy code, then tidying it up, is often faster than writing 2 dozen lines themselves?

I don't know that they have.

The problem is not that it's not faster but that this causes a deep influence on the code, as well as being full of bugs that are glossed over in the thousands of lines of code.

Claiming it does not have any uses at all seems like an expression of your own lack of creativity

LOOOOOLOLOL pot meet kettle.

But that doesn't mean it cannot simplify and enhance skilled workers that understand its limitations and use it to increase their own productivity.

It can't. It can only be used to generate lazy bug-ridden garbage.

Is it possible you're so engrossed in anger and disgust at how it is being marketed, that you're deciding to hate the entire concept

Is it possible that how it's being marketed makes makes you overlook the bug-ridden garbage that it pumps out?

No, it's possible that I used it and found it to be wrong a majority of the time and that actually just doing it myself is faster and less error-prone. If you only want to pump out trash then by all means. But I don't want any part of it.

If hammers were used

I'm so tired of this nonsense. A hammer does not do anything that I do not explicitly make it do. I do not ask a hammer to install the roof and then it runs around driving nails into all the windows.
