Wasn't it specifically stated that the Allagans created Omega, though, in order to defeat and contain Bahamut? The Allagans didn't exist outside of Hydaelyn's realm, so why would their creation? Does this mean that the Omega we're fighting in the Rift is not the same Omega that we just recently activated to fight Shinryu? This is pretty confusing if it is the case.

Perhaps the Allagans FOUND Omega, and rebuilt/repurposed/enslaved it as a Primal hunter?

It seems like the "Allagan origin" of Omega has been quietly scaled back since the Lore Book release. Recall that we've never been told by an infallible source that the Allagans created Omega - Eorzean scholars just discovered it beneath Cartenau, and assumed it must be of Allagan make.

In truth, however, Teledji Adeledji's aim was not to claim the Cartenau Flats itself, but what had once been buried deep beneath it: Omega, an Allagan creation not unlike the Ultima Weapon, which had been laid bare by the destruction wrought by Bahamut during the Calamity. Allagan inscriptions indicated it was created to contend with the dreadwyrm himself, and were someone to harness this relic, they would have the strength subjugate all of Eorzea—or so it was feared.

Emphasis mine. We've been told that the Encyclopædia is written by Eorzean scholars, who are fallible. We're told it's an Allagan creation, but the only hard evidence we seem to have of this is that it was accompanied by Allagan inscriptions mentioning a "dreadwyrm" and found beneath the Allagan hulks in Cartenau.

Note also: the Lore Book's account of the defeat of Bahamut says that he was defeated after a long battle of attrition with Allag's horde of voidsent-possessed zombies - Omega isn't mentioned, yet other accounts seem to credit it with Bahamut's defeat and capture. Maybe the "dreadwyrm" in these Allagan inscriptions doesn't refer to Bahamut, but to something else... another big dragon which is classically in opposition to Omega in the Final Fantasy series?

I'd love to find out the origin of the "Shinryu" of Doman folklore. A member of the first brood? Midgardsormr? Something else?
