I have a room with OSB on the walls and ceiling. It has two thick coats of KILLZ or Zinser sealer painted on it. It is not old OSB it was bought a couple of months ago. I heard it can leach out chemicals that can be bad for air quality.
If it is sealed it'll be ok. Heck they been using it on homes for decades.
