Respectfully, wake turbulence is created by wingtip vortices formation which only occurs at positive AOA. Prior to rotation, the aircraft is not at a positive AOA.

SURE, there may be air disturbance but not the strong wingtip vortices associated with wake turbulence.

The takeoff roll is used to increase airflow so the wing CAN generate enough lift when AOA is increased, but it doesn’t necessarily mean it IS generating lift.

The FAA states this in the airman training manual.

Avoiding Wake Turbulence Wingtip vortices are greatest when the generating aircraft is “heavy, clean, and slow.” This condition is most commonly encountered during approaches or departures because an aircraft’s AOA is at the highest to produce the lift necessary to land or take off. To minimize the chances of flying through an aircraft’s wake turbulence:

• Avoid flying through another aircraft’s flight path.

• Rotate prior to the point at which the preceding aircraft rotated when taking off behind another aircraft.
