You're thinking of Iruru now. Elma and Tooru haven't yet fought "on screen" - was referring to the passingly mentioned earlier clash back home between the two that apparently sunk a few islands as collateral damage, actually...
Note that her offhanded claims about dragon lifespans need to be taken in the perspective that we haven't actually been told of a single one able to legitimately claim such nigh-incomprehensible antiquity, rendering the whole thing more of a grandiose boast (something Tooru certainly is prone to...). It's strongly hinted (and seems to be assumed in-universe) that they're functionally biologically immortal, certainly, but that's quite different from any of them yet having such a cosmic lifespan under their belt...
I mean, unless they actually immigrated from somewhere else it's physically impossible for even the most ancient of them to be older than their world. Barring paradigms wildly different from ours, ofc, which are entirely possible given that plane has active divinities and God knows what else; for all we know their planet might have been cyclically created and unmade multiple times in the past already... though at that point it could be asked to what degree their timeframes were even comparable to our linear one in the first place.
