Without knowing the real domain, we can't do things to sanity-check our
understanding of the problem and give good responses. For instance, the
error message you gave is identical to the one you'd get for a domain
which doesn't have MX/A records in DNS: Unrouteable address.
You have to know a lot about the problem space to know when it's safe to
obfuscate and accept that there are many people who won't answer a
question, on principal, even in those cases. I say this as someone who
sometimes obfuscates. ;^)

You are not wrong. And the idea is that the relay, or remote host, is
the one with the "smarts", so it's a smarthost.
But you have nothing which looks to me like a smarthost Router.
smarthost:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
route_data = my.smarthost.tld
It's that simple. You manually route, supplying route_data of the
remote hostname, using your normal remote SMTP transport; you don't do
this for domains which you handle locally. Put this first, or after any
specially-handled remote domains.
You very probably can also add "no_more" to that, so that if it's not a
local domain then no other routers will be tried, and so avoid even
trying any other Routers. If you want to make it more robust, you can
decorate it with "ignore_target_hosts" and bad IP address space (see the
default configuration for an example) and if you're sure that _all_
addresses for any remote domain will use the same smarthost router
(almost certainly the case) then you can also add
"same_domain_copy_routing", which is an optimisation.
