The only available knockout big enough for my #1 wires is on the right side of the panel. The new breaker (double pole 100A) needs to go on the left side of the panel. Can I cross my #1 wires under the service wires as pictured?
Another option is to shuffle breakers around, but I'd rather avoid all that splicing in the box.

Yes you can route the wires under the feeders there is nothing wrong with this. As far as a code reference it’s tough to find something in this case that says it is not allowed or allowed. The wires in a enclosure can even be touching the 1 requirement the insulation is rated for the voltage. both the main and your new wires are probably rated for 600v so you will be fine.
