This doesn't answer your question but my Gdrive is a mess and I'm only one person. Typically I download the the contents on an annual basis in zip files, extract them to a Month/Year named folder on a portable drive and start fresh with a clean Gdrive until the next time it gets out of hand.
I would think Downloading first then using parsing tools locally would make things much easier to organize than doing it through Googles front end.
After thinking a bit more about it, what you probably need to do is make a requirement for all internal emails to be CC'd to a central address then use that address to download and or synchronize itself to an offline drive where perma links can be issued.
