I'm of a different opinion.

1. If you use the first person pronoun "I", you better make damn sure you wrote those words.

2. It's fine otherwise to use LLM words, but I beg you - DON'T SHIP YOUR FIRST DRAFT. Read it, reread it; delete words in it; replace three words with one; replace dumb or overused turns of phrase with fun metaphors; generally give it a sprinkling of joy; break up punchy sentences by making them run-on sentences to trigger your readers' OCD... you get it.

Did I mention not shipping your first draft?
