Exchange doesn't route by sender, only by recipient.
While you could place restrictions on one of the SMTP connectors, all that will happen is that Exchange will reject the email that is sent using the other connector. It will not try the other one.

The only thing I can suggest is that you have two connectors, identical cost on both and they are then load balanced. If you route a lot of email to specific domains, another idea would be to use a connector to route those domains using the ISPs servers.

The reason why I want this is because, our company has had bit of company spilt. One half of the company has changed email addresses and are on a new system. What we want is to still have be able to recieve from our old email addresses, but I cannot add a forwarding rule because we use auth smtp which only authenticates certain domains to send from.
not sure what I can do.

If you have the ability to send email out via the ISP, then route everything that way. There isn't really any other option available to you if the service you are using has a restriction.
