some questions about streaming league

I am an online streamer for the league I usually do normals with my viewers out of US I currently live in a place where people don't talk english and my viewers wanted me to give video reviews for many pro games for NA and Korea. I have heard Riot does not let people show there tournament games do to legal issues from youtube videos. but the same people claiming that statement are recently putting videos out where they comment on pro games which to me does not make any sense. I went am currently looking to see if Riot have anything on this topic on there website but have no success I see many people in the country I live in stream games on there channel and just want to see if I can find anything on this .
