Turns out it wasn't as useless as you thought :-)

LVM does the job of managing storage partitions, but not the "job" of reserving
a gap for GRUB to use.

Furthermore, the scheme you propose looks overly complicated [1] for the task
it's meant to accomplish [2].

Thinking about it, I think the root of your problem is that you would like
your storage system (LVM) to be completely unrelated to your boot system
(GRUB).  But BIOS legacy cruft won't let you do that.  So maybe a solution
that would work well for you is switching to Coreboot [3]?

[1] random-number-chain??
[2] we don't need anything fancy, just an area of disk that isn't used by
    anything else.
