I haven't done a relay driver circuit for, literally, eons.
Where do I look for reed relays that work on 3.3V supplies with
specications for the coil inductance?
Thanks!

Who cares?
Just use the standard RC snubber across the coil; 100 ohms should be
fine.
You should learn to read... it's a custom chip issue. I posted a link
to a proper solution.
BTW, 100 Ohms and a coil current of 33mA would produce 6.6V (net, 3.3V
supply) on the drain, exceeding the 5.5V maximum operating rating.
