When she sacrificed herself to make Hydaelyn, she gave up all the research capabilities that Venat had. Hydaelyn was not Venat. She was a single-minded primal imbued with some of Venat's memories and the strongest aspect of Venat's will (which at the time was to pave the way for future generations to permanently end the threat). There's a huge difference there. She was under a pretty big time crunch, with the world ending, and all. All she did was to set some wheels in motion and hope for the best. Hydaelyn wasn't capable of doing the research that you're suggesting she should have done.

As you said, she decided that rallying the other ancients to fight Meteion was futile for whatever reason. I, too, wish that they could have provided a better explanation for that, but if nothing else, we can chalk it up to sheer panic.
