Indeed, it seems pppd doesn't support getting DNS resolvers in client mode. I've run into the same issue years ago. Nowadays I always use a VPN across such links and just get DNS from the other end of my tunnel. You could try running unbound(8) and make resolv.conf point to 127.0.0.1. That should give you working DNS in any case. For WAN devices supported by umsm(4), the situation is a bit better. The umsm(4) driver shows DNS resolver IPs in ifconfig output so scripts can grab them from there.
