No, because I've never used dracut.

Same question as always: does your kernel have enough built-in drivers/modules to mount the root fileystem on /?
If yes, then you don't need an initrd.
If no, then you do need an initrd.
I don't think where /usr is matters, does it?

My understanding, the whole init thing started with a bluetooth keyboard
or mouse driver that was installed in /usr instead of /bin or /sbin, whichever one fits. I've always had /usr on its own partition until
this time. Mostly because it is easier to put /boot and root on regular partitions and then put /usr, /var and of course /home on LVM. That way
as software like LOo, KDE and others grew, I could use LVM to grow them easily enough.
You need access to the LVM tools to be able to access your /usr. I expect
they will be under /usr - hence you need an early userspace with the required tools to be able mount LVM and anything in it.
Alternatively, use btrfs and do away with LVM.
Given the merge of bin and sbin to /usr, I have no idea if a system will
boot without a init thingy or not.
It won't boot without a initrd if /usr is on a different partition, because
the OS needs commands available on /usr to boot with. Chicken <-> egg
problem.
This is the first time I've
ran/installed a system with those merged. I'd think it would work but I don't want to have a unbootable system to find out it doesn't either.
With a merged /usr you will now also have /bin, /sbin, /lib, /lib64, all of them in /usr.
