Nothing in the Memory items like that (as per the report, page 30). If the runaway continues after AP is switched off, is says to switch off the trim. Nothing about "counter trim with control column switches, return aircraft to pitch neutral then switch off trim" as you are alluding to. And even if they had "disengaged the autothrottle", what would that have achieved? Nothing unless you then pull off a fistful of thrust...
Then you pull out the two page AD memo from Boeing and recall what it said: at the bottom of page two "Electric stabiliser trim can be used to neutralise...".
