It means they can impersonate the Bluetooth device connected. Input devices are particularly concerning (keyboards and mice) as well as BT IoT devices which already historically lack good security controls. A lot of vehicles have Bluetooth integrated as well these days.
I would go with wireguard VPN or something like cloudflare tunnels or tailscale. With wireguard you'll need to open up an external port and forward to your VPN host, but wireguard uses UDP so no one can probe it for responses. CF tunnels and tailscale you don't have to open up holes in your firewall which is nice.
You also have the option of using a proxy and opening up 443 publicly on your firewall, but unless you know what you're doing I'd leave that closed until you learn more.
I would get a domain name and use ddns to update your rotating IP. Then I would setup wireguard VPN in split tunnel and have your parents network tunnel back to your piholes for dns resolution.
I use cloudflare API for ddns updates but there are plenty of choices for that. If you're using cloudflare for DNS just keep in mind you can't proxy the DNS entry for the ip for your VPN host as CF only forwards traffic over certain ports and they are not configurable (on free plan anyway not sure about paid).
+1 for dst nat on googles dns servers back to my piholes
Wait till you plug in your cell phone to charge they start calling home like crazy

We got lasik for my fiance and that was hands down the best money we ever spent. Life changing really.
Who's your DNS provider? I use cloudflare and powershell script and hits their API. Works well
