Intriguing to use AI to draw it all for you - certainly could speed up things - I'd need to thoroughly check a few times to gain confidence in the process.
My approach is slightly different generally. Recent PDFs done with CAD allow you to convert to lines, arc, and so on but the accuracy might be off. I'll scale the PDF, convert and then snap entities to a grid again - often 1.25 or 2.5mm - and that usually gets the right result... on a PDF that can be converted. A mix of both, yours and mine could get good results.
Our biggest problem is historic records - scanned paper copies originally drawn in pen and ink - now that would be a good work out for AI !
