Have you looked into in the system preferences under "Security" whether you have to (re-)enable the extensions?

Another option:
Try to completely uninstall OpenZFS and then reinstall again. Don't forget to enable the extensions in the system preferences and the necessary reboot of your machine...

I've had twice such a situation. My solution is simpler if it works for you. It is, I admit a bit strange:

First load the extension manually:
sudo /sbin/kextload /Library/Extensions/zfs.kext

It may either work or tell you a reboot is needed. If reboot is needed, just reboot and it will work.
