When I boot and enter the root passphrase, I see the following warning
anywhere from two to a dozen or more times:
cryptsetup: WARNING: sdb2_crypt: couldn't determine device type,
assuming default (plain)
What is causing the warning?
How do I fix whatever is causing problem(s), so that no warning is
displayed?

This appears to be the result of the Debian installer assuming that
everyone uses suspend/ resume and the suspend image is stored in the
swap partition.
One work-around is to edit /etc/default/grub to disable resume:
GRUB_CMDLINE_LINUX="noresume"
It also appears that the GRUB settings are stored in two or more places
-- text configuration files and binary files -- and the binary files
must be rebuilt whenever the setting change:
# update-grub
