Sod's law says there will be at least some crosswind, and if she has no idea how to stop, sod's law also says that there will be something unpleasant in the way after touching down at 60mph and then veering off the runway.
ISTR that the successful talkdown by a FI in Tower and a shepherding RAF Sea King of a non-pilot at ?Humberside after nightfall, after pilot had collapsed, had not confused him about steering on the ground and brakes. Probably sensible not to overload him. Anyway, as instructed after heavyish touchdown he did close the throttle, and presumably tried (obviously unsuccessfully) to steer with yoke as he had been in the air. He slewed off the runway, slowed down rapidly on the grass, and may have damaged undercarriage, prop and possibly more. But he survived, that's the main thing.
Damage, with survival and maybe minor injury, is probably acceptable in these circumstances, although ground manoeuvring would probably be included in a properly structured course. But with throttle closed, excursion into presumably long grass would bring aircraft to a halt fairly quickly, and would probably not lead to major injury. If the aircraft is reusable, that's a mere bonus.
