I use lui v3 which has oUF embedded raidframes i was wondering if any/all of the oUF pluggins like raidDebuffs are compatible and will work with it? as it doesnt seem to have it already built in to the extent i need....
Assuming that the version of oUF that LUI is embedding is compatible with the plugin you'd like to use, it wouldn't do any harm; but unless the oUF layout LUI is using has support for that plugin, it won't have any effect. You'd need to write the code to handle it, or borrow the code from elsewhere.
