No. I'm the sysadmin who put LXD in place. I'm asking:
1. why is this snapshot left behind when I deleted the container?
2. how should I properly remove this snapshot?
3. why are there what appear to be snapshots that I did not create?
Thanks!

But it does appear to be a snapshot. How was this generated? Why is it there? I
see others that have similar naming conventions (ending in a number string that
I didn't create).
So you're asking "what is on my system" to strangers on the internet, rather
than asking your (previous) sysadmin? Right ...

How do I properly remove this without causing any unintended consequences?

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.
