So you're asking "what is on my system" to strangers on the internet,
rather than asking your (previous) sysadmin? Right ...

Quick google search points to
https://ubuntu.com/blog/lxd-2-0-your-first-lxd-container (look for
"Snapshot management")
https://discuss.linuxcontainers.org/t/lxd-3-8-has-been-released/3450
https://discuss.linuxcontainers.org/t/lxd-3-11-has-been-released/4245

Newer lxd versions put snapshots under a diffierent directory (e.g.
/var/snap/lxd/common/lxd/storage-pools/default/containers-snapshots/), so
my guess is you're probably running an old version (2.x?).

Also, deleting containers should also delete its snapshot (tested on lxd
3.17).  There is "snapshots.pattern" container configuration, but it won't
help much since in your case you already deleted the container. So (again)
my guess is the snapshot is something created by an additional tool
(external to lxd. A manual or scheduled btrfs snapshot, perhaps?). In which
case your (former) sysadmin should know more.
