Are there any out there? I can find quite a few with mains powered
sounders but they still have battery powered buttons.

Yes, you can easily buy a bell and a transformer. Likely you can also
modify a battery operated one to use power from a transformer. I
recently did just that using a transformer that had 4,8 and 12v options.

When I replaced the push buttons at the front and back doors I found
that there had obviously been many previous ones. Unlike the other mains
operated one that has remained the same for the past 30 years.

The transformer I got looks like this:
