First of all I don't know anything about OpenBSD but we have to
know, making squid use a particular tcp_outgoing_address is as much
as what we can ask squid to do, actual routing decision should
rightfully be left to the OPERATING SYSTEM. In Linux, all these
things are addressed :-

1. You can use POLICY ROUTING - one of the capabilities of policy
    routing is be able to route based on SOURCE IP instead of destination
IP.

2. You can use MULTI PATH ROUTING - ie you can start a session
    based on certain relative weight you assign to a default route.

3. You can also use netfilter 'recent'/CONNMARK match - they allow
    you to tie a session to an interface for a configurable amount of
    time.

I might not be even exhaustive here.

All in all, my conclusion is this :- You really have to look hard to
the operating system for this instead of squid. If you have exhausted
the capabilities of OpenBSD, you would have to throw it away !
