As others have said, I'm not sure this is a good idea, unless your goal 
is to annoy your users and impede communication.  But one thing that 
would have the side-effect of blocking a reply-to-all is changing the 
list settings so that the list only accepts mails if there is exactly 
one recipient.

You can do this under Privacy Options -> Recipient Filters
Set "Ceiling on acceptable number of recipients for a posting." to 1

Then anyone hitting reply-to-all will get a message saying that their 
message is held because there are too many recipients, since any 
reply-to-all will include both the sender address and the list address.
