Strictly speaking no they don't have a soul because in FF14 "soul" and "self" seem to be two different things even though for us in the real world it's often understood to be synonymous.
(I agree that the endless are "selves" btw.)
As far as I understand a soul is an actual "magic-physical" "object" (or entity) that is subjected to certain laws of (magical) nature.
It's a collection of special aether (life force or something else, but it's "something" - very helpful I know) that holds the "core identity" of a person. It also serves as an actual "magic-physical" core for the aether that composes your current reincarnation (your flesh, your memories, your powers etc.)
If I understand it correctly if your soul returns to the aetherial sea the aether that comprises your memories (since you've already left behind the aether of your corporal form) slowly washes away but the core remains.
To my knowledge the core itself can't dissipate. Then after some time this core attracts enough new aether so that you reincarnate as a new person in a different corporal shape. You don't retain your memories and your personality might be different in some aspects but a certain "true core identity" will be constant across all of your reincarnations (e.g., Fandaniel/Amos being a genius etc.).
So according to that logic it is probably possible to be a self without a soul in FF14, e.g. by extracting memories and infusing them with external life force to give them enough/the right power to reinstate their consciousness.
Now what confuses me is that
the soul and their life force seem to be two different components as well. Because on the one hand Alexandrians consume the life force of purified souls but Erenville also believes he'll see his mother in the aetherial sea (and I believe he was a mouthpiece of the writers in that moment because that scene was there to give us closure/a happy ending). So despite her soul's life force being consumed (and her memories being extracted) Cahciua's soul (the core that holds her true self) is still intact and inside the aetherial sea. (Technically this means that if Erenville's soul finds Cahciua's soul in the aetherial sea he can't tell her of all his travels because her memories had already been removed in S9 and she doesn't remember her old self and life. She isn't the reincarnation that was Cahciua anymore...)
Either way, perhaps if your life force is depleted, your "energy-less" soul with your core self remains and recharges in the aetherial sea, in addition to attracting new aether for reincarnation.
(But I'm really not sure. Feel free to correct me if you understand wth is actually going on here.)
