I think you're in luck here. You can use XMPP or Matrix as the other person said, and pick from the myriad of different servers to let the authorities play whack-a-mole with them. If you're picking XMPP, suggest them one of the clients that support OMEMO (it uses the protocol used by Signal too). Briar is another good option, since it uses Tor, but you both need to be online in order to receive messages from each other since it uses no servers (unless they and you use something like this on a spare phone).
An option that would likely be a better fit for what you're looking for, but which I haven't tried yet is SimpleX.
Whatever you pick, I think it would be a great practice for you to teach them to use a panic button app such as Ripple (not sure if that's maintained anymore though).
Wow, thanks a lot! I'll look through the options!
You're welcome. Stay safe!
