There are several different definitions of AI going on here, creating vs. editing.

I own a lifetime license that I got super cheap 4 years ago or something called ProWriting Aid that I for spell checks and grammar stuff and style. I simply could not live without it. (I write professionally.)

I also got a ridiculously cheap lifetime license about a year ago for something called Designrr, and it absolutely blows my mind. For the rest of my life I have audio transcription, a writing aid that is also capable of formatting a book with a TOC, a research assistant, audio books, ebooks, an inhouse designer, and on and on.

I use Joanne Cooper's LyricLab sometimes to help me format my finished lyrics so I can pull them into band in a box easily. I could do it myself in wordpad but it's just a lot faster if I use LyricLab

However outside of that I have found that it's absolutely impossible for me to write usable lyrics of any sort using any type of AI.

The only thing that works for my songs, and this might be different for other people, is one of four techniques, sometimes several at the same time.

1. I have a guitar at my lap or I'm sitting at the piano staring off blindly into space just tinkering around and all of a sudden lyrics start spilling out and I have to find a piece of paper immediately to write them down or turn on the microphone and record myself babbling.

2. I am listening to a band in a box backing track that I have created and I'm staring off into space incoherently babbling and all of sudden something comes into my head and I have to use the same technique as in number one.

3. I'm staring down at a notepad or piece of paper with a pen in my hand trying to craft an idea that I can hear with words in my head but it's kind of foggy. After I write it down 30 or 40 times and keep scratching stuff out it finally comes into shape.

4. I'm driving along in the car and all of a sudden a complete song with music and lyrics comes into my head and I have to immediately grab my phone and sing it, words and Melody at the same time, at which point I can't wait to get back home and get in front of band in a box and start putting that chord progression together.

These are the only techniques that ever worked for me where lyrics are concerned.
