Maybe. Many hot Jupiters are probably tidally locked, but it's not clear to me whether rocky planets will be tidally locked. Though given that they're considering timescales of 100s of Gyr maybe they will end up tidally locked by that point. At any rate, I don't think our understanding of tides is good enough to claim that they will or won't be tidally locked one way or another. But needless to say, the authors didn't consider details like this in their paper.
