You can't give a definite no to that because, since gravitons have stress-energy and are non-perturbative, a field theory advance that worked for them could also help with the strong force.
I mean sure, since we don't know what GR + QFT could look like, the result could be just about anything and somehow give us nice closed solutions to QCD problems. But I don't feel like that line of reasoning is particularly useful.
AdS/CFT is already an example of an approach to gravity yielding an approach to strongly coupled field theories.
It's an approach to a hypothetical other type of universe's gravity..
