It has it's own internal queue directory, yes. But it does not
deliver directly to the MTA mqueue directory, no. Instead, it hands
the message off to the MTA that it is configured to use -- usually
port 25 on the "localhost".

Not correct. The easiest way would be to run two copies of the
MTA on your machine. One copy listens on port 25, and runs normally.
This is for inbound mail.
The other copy of sendmail listens on a different port (maybe
port 26) on the "localhost" interface only, and on the command-line
you give it a different configuration file to work from -- that
configuration file causes the second copy of sendmail to work in
"queueonly" mode, does not have any queue runners, and has a
different mqueue directory. You then control the queue runners for
that second instance of sendmail yourself.
You then configure Mailman to deliver all outgoing mail to this
second copy of sendmail.
I still think that this is not a good configuration for doing
throttling, because you have only indirect controls over the number
of message deliveries that occur in a given unit of time.
The milter technique would be a much more direct method of
control over throttling.
