Wow, it'll be interesting to see how long it lasts. That is presumably not the expected usage pattern.
As you said, very unlikely it has an oil pump. Adding a pump? Probably possible, but sounds rather involved & risky.
He could keep an eye out for a used generator with a filter, I guess.
My inclination would be synthetic, but I'll bet it doesn't matter much here. You won't be wearing the oil out, you'll be replacing it due to particulates, etc. You could also extend the oil change intervals, if they were too cumbersome.
I would definitely put a magnet on the drain plug. Definitely change the oil after a few hours of running, to remove break-in particles. After a few scheduled oil changes, perhaps the rate of particles would reduce, maybe you could get away with some longer intervals. And not all unfiltered engines are 20 hours. My little Honda EU2000i generator is 100 hours, after break-in. First change suggested at 20 hours (personally, I'd do it after 2-3), then every 100 after that.
