The point here is that you are targeting such a ridiculously tiny edge case as to make it incredibly implausible. Either:
1) The SLN is so hidebound that it will ignore the need to build matching light combatant capability as the Alliance, in which case it will continue building its usual classes; or
2) The SLN recognizes the need to build matching capability, in which case LACs are back on the table.
A frigate is barely more than a LAC with a hyper generator piled on top. If you are positing that the SLN is capable of radically rethinking its ship design paradigm enough to even think about resurrecting a dead and buried ship type, then it must also be capable of recognizing that building a frigate without the hyper generator (i.e., a LAC) is at least equally desirable, especially given that it knows that the Alliance has
also gone to building LACs. And since the SLN knows that it LACs are much cheaper than frigates, and frigates have zero advantages above and beyond hyper capability, I see no reason why they would not go go to LACs first.
The SLN is not going to look at the capability disparity and decide that it wants to build supremely cost inefficient platforms to carry out the missions they need those ships to do. As pointed out in that infodump, frigates have no justification regardless of the tech level, which is why they disappeared from the major navies in the first place.
If anything the SLN is not going to recognize the need for LACs until it is too late. Instead they are going to follow the same convergent design evolution as Erewhon/Maya and build better destroyers, not frigates, to get that defensive capability. The difference in construction time and crew would be minimal over the frigate, but would buy them so much more in capability.

In such a case you may well need smaller vessels like a Frigate to substitute for a LAC and free up heavier vessels for other duty.
As I've said before, you can't use "cannon gospel truths" about what makes sense for the RMN and attempt to apply that logic to the SLN because the two are operating under radically different realities.
