Can’t use on my smart Tv (lg) YouTube app. Can’t broadcast from phone app to Tv

This seemed like a great idea, but if I can only watch it on my computer or phone, it isn’t worth it. My Tv has a YouTube app but apparently it doesn’t support YouTube tv. I don’t have a chrome cast and I’m not going to buy one, nor can I share the screen to my tv via WiFi the way I can using the regular YouTube app. This all seems very limiting. I will be canceling after the free week.
