You can get the latency down to a second or two by adjusting the buffer
sizes in the icecast config.

HTTP streaming with sub-second latency isn't really possible on the WAN.
If you need that you'll have to switch to an RTP-based solution.

There's no great opus-supporting server solution for that. The code at
webrtc.org can do this, but afaik there's only glue code for browsers as
clients. People are working on reflectors and stand-alone source
clients, but I don't know of anything I can recommend at this point.

You'll probably have to write some code if you want this to work.
