If you have an LG TV that's 5 years old or less, you should be able to get 3 months Apple TV for free.
I previously was a subscriber and was able to subscribe again for another 3 months free.
How to get:
Open the Apple TV app in your smart LG TV. It must the LG Apple TV+ app (not Chromecast, Fire TV or other streaming device, etc.).
Download the app if it's not already on your TV
Once you do you should see a message as per below picture
