You know 2.4 confirmed that Louisoix is not enthralled by Bahamut only that he is actually working with Bahamut... AS A FELLOW "PRIMAL" that's right you heard me a Primal so Louisoix is not an aetherial image made by Bahamut but from himself and as for the White Raven he is indeed a thrall to Bahamut and it is most likely that Louisoix himself resurrected him with Bahamut's own power in a way it makes sense because Louisoix is now the Primal "Phoenix".
