Low Noise Amplifier and Input/Output Phase
One does not usually place an LNA inside an RF feedback loop, so as long as the group delay across the frequency range of interest is reasonably constant (It generally is) it is just not that important. Also LNAs cannot in general be assumed to be small compared to the operating wavelength, if I need to tune phase at 24GHz I do it with a short length of transmission line...  

Opamps are basically always used inside a feedback loop which makes phase shift in the naked opamp basically only a concern for stability but not one that impacts the overall phase shift of the circuit because the feedback loop defines the phase shift as long as there is sufficient open loop gain (Opamp circuits are pretty much all electrically small).
