I have seen some people using dhclient as a templated service configured
to trigger when the device shows up (e.g.
After=sys-subsystem-net-devices-eth0.device +
Requires=sys-subsystem-net-devices-eth0.device).

This kind of setup might be desirable in very basic custom
configurations where the full network "initscripts" are not needed.

But to answer the OP's question, no, there are not units for dhclient
that are shipped with systemd. You may find some examples of units for
dhclients that some people have created for their custom setups however.
