Is 'Hydaelyn' a misnomer based on a misconception?

Hmm, no, I think for the term 'god' to mean anything, it has to connote a being outside the created order, upon whom the created order is dependent. I don't think FF has ever posited the existence of such a being(s) in any of its iterations. The games generally take an anti-theistic stance, wherein supposed gods turn out to be in some manner fraudulent, or outright malevolent. I don't see XIV being an exception to this.

FFXI, which at least early FFXIV was based on, had Altana. She was an unambiguously good true goddess and like Hydaelyn, is connected to the Mothercrystal. In FFXI, Altana split the Mothercrystal into shards which sundered paradise and created the world we know now as Vana'diel. Sounds very familiar to Hydaelyn shattering the world into shards.

This seems like a legit example of an unambiguously good deity, so I'll grant that. I couldn't find any info about her sundering paradise, though? From what I could tell, there were already multiple mother crystals when she created the original sentient race, and then she created 5 other races after this original race was confounded by Promathia.

Hydaelyn just feels like an advanced version of an Allagan drone (very advanced) that's a bit confused about where its maker has gone and not quite sure what to do so just keeps going with its original program. She even sounds like a garbled AI in Heavensward. I remember doing the Praetorium for the first time and wondering why she was so obsessed with just one thing. She literally never talks about anything else ever. It is creepy and a bit insane-sounding, and so I have always been wary of her. All the revelations that have come since have only deepened this for me. Which is why I say I hope there's some convincing story telling on the way if she is going to turn out to be Mother. I know they can pull it off because I loathed Solus in SB. Absolutely loathed him. But I loved Emet-Selch

I really like this way of framing things. I have long thought that characterising either Hydaelyn or Zodiark as good/evil is wrongheaded, because this would imply moral agency, and I don't think that they—or any other Primal—has any. So far as I can tell, Primals are born with essentially one-track minds reflective of whatever fixation(s) their summoners had associated with the imaginary object of their summoning. Primals are not good or bad: they simply follow their programming. The consequences which ensue from the execution of that programming, on the other hand...

Correct, paradise was gone by the time she created the Zilart. But the living world was created by splitting the mothercrystal into 5 pieces. The Zilart wanted to go to paradise and attempted this by encasing the mothercrystals in cermet (the crags) and connecting them together and sending the energy to one place to join them together again and destroy Vana'diel and bring back paradise. But that would end the world and bring back the dark god Promathia so they were stopped by Bahamut, the Kuluu, the Dawn Maidens, and the summons. The only time Altana ever gets involved in the story is when you beat Promathia and then Altana beams him to death.
