I can't imagine that Gnu LVM wouldn't escalate complications of the complicated
environment that multiboot is.

Typically it's either LBA sector 0x1F or 0x3E.

That sector contains information not available elsewhere, originally intended for
constructing IBM BM's boot menu and functionality, with OS/2 LVM data later added.
It wouldn't prevent using Gnu LVM, but neither could it assist with cataloging of
Gnu LVM content. Gnu LVM would be an extra layer only accessible via Linux tools,
entirely outside the scope of what works for me now.
All this disregards the issue of LVM's physical discontinuity when sector level
rescue operations are indicated by the gap between failure and most recent backup.
This alone would keep me from considering its addition here. I'm well beyond a
point in time when any change in routine could be considered anything but hostile.
I strongly resist fixing what ain't broke.
