You can enable debugging in your pppd config which may help.
There is also a "usepeerdns" pppd option that may give you some joy.
I have a client who has a prison as a customer and they have lots of
unusual requirements for computers inside the wire.
I have debugged hundreds of PPP clients/servers over the years so if you
want some help feel free to reach out and contact me.

Thanks, all. Yes, there has to be a DNS, but there's a chance that

(yes, it's that kind of place)
There is no other internet connection. We've been given a host name,
not an internal IP address to connect to. We're also hearing that
we're the first folks connecting via this ultra-locked down LTE
network for IOT devices, so maybe they forgot to provision some services

PPP does not require a dns server address to be provided.
But most folks do provide one because it would make for LOTS of
support
calls to not hand out your DNS servers.
Is there a DNS on the network that your connecting to at all?
If not then you wll likely be forecd to use the /etc/hosts file to
add
in the IP addresses of the target systems.
