The initial application of rudder to counter an engine failure is very different and employs the same rapidly deployable muscle memory that a pilot has used on all twin types from the start of their twin flying.
Trim runaway isn't obvious, but resulting trim force on the control wheel is. I believe this is why the first crew and captain of the second crew correctly responded with countering amounts of trim to maintain the pitch trim manageable. Looking at the trim wheel and trim indicator, just like looking at all the other instruments as the pilot monitoring should be doing, will tell the crew what is happening. The third crew did not completely counter the trim force change. Training should include looking at all the indicators, not just the glass ones.
