Cliff notes answer:
It appears that time spent in an ultralights that are LSA (Light Sport Aircraft) counts towards 'total time' and maybe some single engine time as well. This is based on the definition of ultralight as an aircraft and it's got a lawnmower engine, so technically it fits the criteria.
Any pro want to weigh in? I don't fly ultralights, so I've got 0 experience in this arena.
