I have tested this:
if vol name is different than "subvol-......" the LXC container can't start:
rpool/RESTORED/vm-200-disk-1 -> starting error
zfs rename rpool/RESTORED/vm-200-disk-1 rpool/RESTORED/subvol-200-disk-1
rpool/RESTORED/subvol-200-disk-1 -> Start OK
( in both case i have the correct .conf file with correct rootfs: )
I hope this help someone that restore a disk with different name
