Hello. Help me figure out what the disk is full of? My virtual machines and backups are stored on different disks.

That's just that your lvm storage pool is nearly full allocated into 3 volumes root, swap and data, see
lsblk, pvs, lvs, lvdisplay. As you have no vm/lxc in data yet the usage of data is 0% acoording to your second picture.

I don't quite understand. Proxmox is installed on a 500 Gb disk. For VM, a 500 Gb disk is used (d1 storage), for storing iso, a 2 Tb disk is used (T1 storage), for backups, a 2 Tb disk is used (backup storage). What exactly takes up space in LVM?

The space "97% assigned to LVM" is not really used as think about it's just another level as like partitioned and is just confusing. Your systemdisk has 3 partitions, Bios+EFI+LVM. The LVM partition again is say partitoned again into Swap+root+LVM-thin(called data) until up just 3% reserve which shows you "97% assigned", see "lvs" and "lvdisplay" output. If you don't have a vm sitting in the "lvm-thin data" then it's still empty but is defined there, eg. lines from lvdisplay to vol data:
Allocated pool data 0.00%
Allocated metadata 1.59%
