I could not find anything in dracut that modifies lvm.conf, but looks like
dracut calls the lvm commands with `--ignoremonitoring`.

To date this is not handled in lvm2's mkinitcpio hook... Wondering if
that would help. Oleksandr, you could undo the udev workaround, then apply
the following diff to /usr/lib/initcpio/install/lvm2, regenerate the
initramfs and retry?
