Good effort, but the arrangement isn't quite right yet. However, it can still be improved.
I also gave it a try and the AI assured me that it used the same chord symbols as in BIAB, but when I entered them into the chord sheet, that turned out not to be the case.
Yes, you can still create the chord families suggested by the AI: triads, sevenths... and I ended up with 10 groups, but then there are gaps in the chord sheet
But then you need to know exactly which system BIAB uses for notating chords in the chord sheet before the AI can get to work on it.
