I was reading the RabbitMQ page on the MQTT plugin earlier:
https://rabbitmq.com/mqtt.html

That page says you have to manually enable the plugin in order for it to
work. Once it is enabled there is no reason Mosquitto wouldn't work with
it. They both support MQTT 3.

There is also a RabbitMQ C library that provides support for AMQP. It is
available here:

https://github.com/alanxz/rabbitmq-c

And this page seems to have some information on using it:

https://www.cloudamqp.com/docs/c.html

I haven't looked over the source code to see how easy it would be to wrap
in LCB though.
