Are we even sure TTGL's size can be taken at face value? I mean, it's definitely huge, but there's evidence to suggest it's not quite as huge as one would think. Consider that the fight takes place in an artificial reality created by the anti-spiral. The "galaxies" used for size comparison aren't necessarily guaranteed to correlate to our own. And there is some ground to say that they don't.

The first thing to come to mind come from a bit earlier, when the Super Galaxy Gurren Lagann was fighting. That thing is established as being the size of the moon, in that it was disguised as such for a while. However, during the fight, one of the anti-spiral ships throws "planets" at it, which are much smaller than it is. That planets in the Anti-Spiral universe would be smaller than the moon in ours suggests a size discrepancy.

More notable, however, it something from the last battle.

That's the Anti-Spiral mech, which is the same size as TTGL. That ball in its head is the Anti-Spiral homeworld. In order for that mech to be galaxy sized, that planet would have to be much, much, much bigger than a planet ever would be. On a scale that really is quite hard to describe.
