Several generations down the line there should not be much problem. Also keep in mind that while effectively a genocide, it was not a complete genocide, since non-bending nomads still existed by the time of AtLA, meaning that their genetic legacy may not have been completely destroyed.

Additionally, it has been strongly implied that bending ability is not completely dependent on genetics, so potential airbenders may yet exist in the Earth, Fire and Water nations; however, without training, they remain undiscovered.

As yet another alternative, there may be a forgotten group of airbenders in the world who were not affiliated with the air nomads/monks, much like the waterbending tribe of Foggy Swamp in the Earth Nation.
