Logs seems to confirm what you said. I see correct logs and even some initial frames, but this is immediately is followed with usb device remove event.
Also in system logs I see usb hub errors. Most likely usb hub is bricked.
You can confirm this by doing following experiments.
1. Detach monitors from DisplayLink dock
2. Connect other usb device(e.g. pendrive, mouse) to the usb3 port of the dock.
3. Connect Ethernet cable to the displaylink dock
4. Connect device to Chromebook
5. After a while attach monitor do DisplayLink dock
When you observe that issue does that devices(pendrive, mouse, ethernet) stop working as well?
What I can suggest is to try other usb port in yours Chromebook. You can also try to connect DisplayLink device using usb2 cable.
