They certainly did have the training, and the procedure for unwanted stab trim hasn't changed; the steps are the same, the actions are the same, and it's not like it's an obscure unknown. The cause is irrelevant as the procedure remains the same.
They verbalized it: we know this because it's on the CVR. They did the procedure.
Then they undid it, let the aircraft accelerate well beyond the certification limitations for the airplane, and drove themselves into the ground.
The porpoise maneuver to unload the stab was not taught. I agree they should have pulled the power back. However the full recovery was not trained and will only be trained for everyone after Boeing releases it.
