no extremely rare Pokemon live in lilycove city, but you can get hardish Pokemon from there, and there are some rare Pokemon that live on the route on the west of it.
you can get staryu by fishing on the beach with a super rod, but its quite hard to come across one.
there are some rare Pokemon in the safari zone.
when you defeat the elite four, latias/OS (depending on the game) can be found on the grass on the route to the west of it.
and that's about it! :)
