"I'd love it if any proprietary driver was independently auditable and openly documented like *all* free software drivers. But that's just not the case."

By "just not the case" I assume you must be refering to all free software drivers being openly documented and independently auditable. A great many drivers, graphics/X drivers and otherwise, are either filled with black voodoo that nobody but the author understands (and who is under NDA) or functions as little more than a loading mechanism to push a binary blob of firmware to the hardware.

Then those drivers are also non-free.

Yes, many such drivers are mistakenly distributed under the GPL or other free software licenses. While a free software license is necessary to make the software free, it's not sufficient. Software for which the source code is not freely distributable is non-free.

What drivers are truely Libre?

I wonder what drivers are truely free in the sense that is wanted by people. My experience that a lot of the voodoo with hardware starts with the manufacturer who found what values worked for them and have no idea what happens if you change bit 37 to 1 beyond it blew up Jo in testings monitor.
