Every email message has a from. You can't eliminate that. Anyone reading the message can reply and their message will go somewhere...

You can define an authorized sender for the list, being an email address that does not actually exist in your system, something like [log in to unmask] perhaps, then arrange for the announcements sent to the list to be from that address. Then if a list member replies your email server will reject it with a "mailbox not found" error message, then the list member will realize that doesn't work.

True. But the primary intent is to avoid replies to the original sender address.

If it is unavoidable that there�remains undesired information in the headers, then so be it. As long as any user hitting "reply" in any mail client will not send anything to the original sender.

How should I approach this?

IMHO, you would need a second email account authorized to send mail. There are so many options and variables otherwise that would subvert your intent.
