I would coat it with Kilz before applying any kind of paint.
Or Zinser Bin. Bin is shellac which will seal all smells and even oils and crayon. The problem is the other side will still smell and gas off.

I used OSB to sheet my shop, walls and ceiling. Its a bear to paint with a roller, you need to put the paint on heavy to get into the little divots. I tried a Wagner airless sprayer with the proper nozzle for latex. Worked great and used half the paint. Did it in two coats, some of the chips bleed into the paint, guessing heart wood. The first coat helps seal them, the second coat shows less bleeding but still some. A few years latter I had a wall cleared off when I was installing a car hoist, thought I'd freshen up the wall. That wall rolled on effortlessly and no more bleed. The ceiling was getting yellow from dust and fumes. Rolled it as well, again effortless once you get it sealed.

But the stuff from 20-30 years ago rotted, and turned black from heat (hot sun). I know about that I had to repair some of it, I know that my entire sheathing is garbage. the new stuff doesn't rot like that. But it is less smooth. I'll take less smooth over rot.Times (quality) have changed. The OSB that my son installed in my small shop and in my larger shop some 20 years ago was far easier to paint than the contemporary garbage.
