My PowerBook G3 has a Family Number printed on the bottom. For my Mac, it is M7572. When I enter it here
and click Lookup, it gives me links to the profile pages for my PowerBook model, which includes specs for the graphics hardware.

Do you mean how to find the manufacture of the LCD display itself, or the video hardware config on the logic board?
Finding the code for the vendor who made the display requires an OS because it is accessed through the Terminal app.
If your serial number starts with "W8" and you are having lines show up, that is a known problem associated with the plant in Shanghai China. It also affected a large number of G5 iMacs. Only a new display will fix it and that probably costs more that any used G4 Powerbook is worth on the used market.
