cosmos-omnibus should not start if it fails to obtain (download/extract) the snapshot

It should fail to start when it is unable to download or extract the snapshot instead of starting the node.

This happens when Pod restarts but the snapshot is gone. (when ephemeral storage is used).

And Pod restarts aren't rare. Pod can restart due to provider maintenance, when pod takes up 100% of allocated ephemeral storage space.
