"EDFs/BDFs do not cause torque roll."
I have to disagree.
A single EDF/BDF will certainly create a torque roll effect. Not as much a prop but the motor torque has to be resisted somehow unless there are sufficient 'vanes' in the duct aft of the fan set to completely counter the torque. For most EDFs the exhaust duct is kept as obstruction free as possible.
An example of EDF motor torque at slow speed.
Once sufficient airspeed is obtained the normal controls have no trouble countering the motor torque.
The biggest EDF/BDF effect is the lack of 'prop wash' over the tail surfaces that provide a significant degree of control at low or even zero forward speed like in prop hanging.
