Pretty sure not. I'm receptive to ZFS and have used it in a few projects.
Openwrt tends to focus on (devices with) smaller flash drives. Other FS better
suited to such env.
No ZFS is in available software packages today, in any case.

Has anyone tried to package ZFS (more correctly, OpenZFS) for OpenWRT? Is
there any interest in doing so?

you could always run openwrt as a vm under a hypervisor, for example proxmox.
then you can keep openwrt without any extra packages like zfs and create extra
vms as needed, proxmox already supports zfs if im not mistaken.
if your lucky with the iommu groups you might even be able to pass thru one or
more physical network interfaces to the openwrt vm directly.
I can't assume that the underlying hardware supports virtualization or does so
in a meaningful way. Some of the platforms I'm looking at are resource lean.
I threw out the Xeon-D as an example as my prototyping hardware, but I'm not
going to assume that everyone has comparable hardware.
ZFS is anything *but* resource lean, though.
It's actually more lean than most think.
Lots of outdated information from the old Solaris/Illumos or BSD's
version of ZFS is still preached as gospel in some influential circles
(*cough*TrueNAS forums*cough*).
For example the most common rule of thumb aka "1GB for 1TB of storage"
is outdated since OpenZFS on Linux 0.8 (released in 2019).
Also, while by default ZFS is occupying half the available ram as cache,
that's just a default setting that can (and in most cases should) be
changed depending on your needs.
For example this person ran a 2TB ZFS with the RAM cache limited to 64MB
(the minimum possible) on a tiny RiscV board with 512MB RAM. And in his
benchmark it still ran slightly better than ext4 for non-encrypted volumes.

I have also ran some resource-contrained NAS PCs where I had limited ZFS
to use only 512MB of ram and it is still running fine for 8TB arrays.
