It appears to me that ZFS or LVM actually has some logic to check for actually existing zpools or logical volumes.
In pve 7.3x, is there a difference between directory and btrfs in the menu under Datacenter>Storage>Add?
 
Didn't used btrfs with PVE yet. But as far as I know, a directroy storage won't make any use of the features of the underlaying storage. The documentation lists that a btrfs storage will support snapshots and a directroy storage not (except you use qcow2 files where the snapshot mechanism of qcow2 will be used). So I guess if you want to make use of those btrfs features, like the native snapshots, you should choose the btrfs storage.
