LVM referenced during boot, not my choice?

Hi,

Looking at my dmesg log, I find two entries that intrigue me:

[ 3.371716] random: lvm: uninitialized urandom read (4 bytes read)
[ 3.379372] random: lvm: uninitialized urandom read (4 bytes read)

As far as I know I have chosen to live without LVM for a while. The reason for the warning is another story I think, and if unrelated, deserves its own topic some other (random?) time.

I have deselected the following option in the kernel config:

[ ] Multiple devices driver support (RAID and LVM) ----

This is all I could find. A couple of questions I have now:

Is there something I've missed?
Is the lvm abbreviation not referring to the Logical Volume Manager?
Is it not kernel related somehow?
Edit: Would urandom assume lvm and therefor always generate something? Or would another process assume lvm? Two questions that popped up in my mind, after posting.

My configuration details:

Kernel 5.4.48-gentoo
Running btrfs
A lot of disks inside this setup

Thanks for reading, if you have something to mention, please do :)
