Are you saying oil was off the stick?
if so the engine must have been really low on oil when running previously.
What has drained down will be spread about the innards on start up leaving even less for the oil pump to pick up especially in flight, air cooled engines also use oil as a coolant so there was double reason to worry.
Move on find another SFH, the reply you got if as quoted shows a rather cavalier attitude to your safety.
Personally if I was hiring out the helio I would have a walk round either myself or by the Eng just in case the next hirer was a bit lax & forgot to do what are basic checks.
I don't fly a 22 but is it not a requirement to ch oil as part of pre flight?
And if you say you are worried about an over T as well as other problems why ask you know the answer.
