Alignament change refers only to creatures marked with an asterisk. This is a layout error with d20psfrd. If you look at the original sourcebook (Monster Summoners Handbook), or Nethys, you can see it clearly. So no Lawful Good succubuses. Which is a shame.
I think I saw a discussion where it was concluded that a demon would still keep its Evil and Chaotic subtypes if it changes alignament. Though I don't remember even if it was 3.5 or Pathfinder discussion so...

It could of been either. The rules are the same.
Evil Subtype: This subtype is usually applied to outsiders native to the evil-aligned outer planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields are evil-aligned (see Damage Reduction).
So a Lawful Good succubus (evil and chaos subtypes) would detect as and be affected as a lawful, chaotic, good, and evil creature all at once.
Nice find Jeraa!
Poor succubus, her build is not looking very optimal :D
