Your all hung up on thrust causing pitch changes because you read news articles by reporters with zero knowledge. Thrust changes are a non issue at normal speeds! If you have a trim runaway you need to slow down to reduce the effectiveness of the stab and reduce control column loads. L/D max or probably about 215 knots would have been my target airspeed with trim issues.
Don't forget that slowing to about 250 knots also allows the control system to use full elevator travel. At speeds above that "blowdown" or "blowback" (choose your desired label) occurs and the system is not able to push the elevator to its full travel limits.
