The only problem here is that they didn't need Bahamut to control them. To quote Alisaie, "The dragon you vanquished earlier (Twintania)─doubtless you noticed the peculiar contraption about its neck. It was likely a receptor of some description, used to enslave the creature. Ancient Allag possessed the means to control dragons, it would seem. The Ishgardians would kill for this knowledge, though to be sure, it could as easily be brought to bear against them. An army of dragons could turn the tide of any battle, as the Garleans once learned to their sorrow. I would not be the least bit surprised if they now sought to exploit this power."

Not only did their technology allow them to send Twintania about to guard their satellite, they had balls bigger than Thal himself, the shackled the dragon's "god." Bahamut can be clearly seen wearing all the same bangles as Twintania in full view of the Burning Circle battle field of Turn 5 on his wrists. In fact, his whole body is infused with Allagan Shackles:



The question you really have to ask yourself is this: If Allag could put a dragon deity on a leash, seal Odin away in a crystal, devise mech that could gobble up lesser Primals for a power source, and so on, what did they fear enough to use a weapon like Bahamut? They had to know he was a aether-gobbling, planet-drinker, heck we in the dark ages have that figured out. What's scary enough to an Allagan to risk holstering a nuclear option, bio-mechanical, rabid dog at your side like the King of the Skies Bahamut?
