Look, we know the Tyranids have to travel between galaxies at sublight speeds. This takes millions of years at the absolute low end estimate. The Old Ones are not old enough to have created the Tyranids because that would require the Nids to have travelled all the way out to at least one other galaxy and back. Again, millions of years (and likely more) will have passed. A lot of millions of years. The Old Ones only seem to have existed a few millions of years before the 41st Millenium according to the very sketchy info we have on them. So unless they have time-dilation technology then the Nids are a lot older than the old ones.
