LG probably can't sue you for failing to get consent from a guest, but the guest can sue you, not LG, for being recorded.

> Have a meeting with the executives of LG in their office

> Sue them for not telling you the TV is recording you

I’m sure this would not work under GDPR. The host surely isn’t a data processor.

LG's purpose is to avoid being sued by the guest, not to be able to sue the customer.
