Roku no longer does this

There's something missing now from your Roku menu...YouTube TV no longer lives there, at least for the time being.

Roku removed the YouTube TV app from its platform Friday because contract negotiations with Google have soured. The breakdown won't affect customers who already have the app downloaded. New customers can still access YouTube, just not YouTube TV. 

Roku has informed their customers that the company is working to make sure existing customers could keep using YouTube TV.

They also said "It is also important that you do not delete the YouTube TV app as it will not be available for download to Roku devices".
