There have been complaints about these Google Launcher ads with Sony TVs for months. It's the reason why I didn't update to Android 9 and disabled all automatic updates.

Sony's "smart" TVs all come with Android TV (now called Google TV). Their top of the line OLED TV Sony Z9J starts at $8,000 in 75" and costs $10,000 in 85".

LG TV don't run Android TV. They run WebOS. So they probably have not been getting those ads.
