Reverse proxies aren’t DNS servers.
The DNS server will be configured to know that your domain, e.g., example.com or *.example.com, is a particular IP, and when someone navigates to that URL it tells them the IP, which they then send a request to.
The reverse proxy runs on that IP; it intercepts and analyzes the request. This can be as simple as transparently forwarding jellyfin.example.com to the specific IP (could even be an internal IP address on the same machine - I use Traefik to expose Docker network IPs that aren’t exposed at the host level) and port, but they can also inspect and rewrite headers and other request properties and they can have different logic depending on the various values.
Your router is likely handling the .local “domain” resolution and that’s what you’ll need to be concerned with when configuring AdGuard.
