That's a typical use.

Mailman has no way to control this. Depending on how you have
configured various settings, Mailman may dump 100 or 500 recipients
or more into what it considers to be a single outgoing message. The
MTA which receives this long list of subscribers might then break
that up into smaller chunks of five or ten recipients for some
medium-size sites, fifty or a hundred or more recipients for large
sites, and lots of smaller sites with just one or two recipients.
Your ISP would look at this flow of outgoing messages, and could
decide to count this in a variety of ways. They could count the
total number of recipients, regardless of the number of messages.
They could count the number of connection attempts, regardless of
number of recipients. They could do something else.
If you want to do rate limiting, you need to do that within the
MTA. Mailman has no features to allow you to control this. If your
MTA does not provide any features to allow you to control this, you
should consider upgrading your account, switching ISPs to one that
does not rate limit you, or moving your list to a hosting provider
