Not for me. I would avoid the whole theft of service approach. I think you are on shaky legal ground, plus it sounds lame unless LDS folks really are easily scared.
Say it is against the Terms of Service they agreed to, and will result in disconnection of service. That doesn’t mean it is a crime. The better approach is probably that unsecured WiFi lets anyone within range capture everything you transmit without encryption, allows them access to your network and router on the trusted side of your firewall making it much easier for hackers, and as you mentioned could cause law enforcement to blame you for bad things someone else did on the Internet via your IP address.

You are collaborating in this theft and jeopardizing your own service as well.
