There are various controls that affect being able to mount or unmount filesystems within jails. See the item on 'allow.mount' item in jail(8). In principle you should be able create a file-backed metadevice (mdconfig(8)), configure it with geli encryption, create a filesystem on it and mount it within a jail. In practice, I haven't tried this, so no real idea if it works or not.
