Airbnb cannot force anyone to accept any guest into their home.
All you have to say is that the situation feels unsafe.
If they say that they are bringing animals before they arrive you can reject them on the basis that they have stated their intent to ignore the rules without going into specifics.
If they show up with animals you can refuse to accept them on the basis that it represents a safety hazard.
The ADA does not apply to private homes. Airbnb has no right to force their arbitrary rules on anyone.
They can, of course, delete your listing without offering an explanation. Perhaps they should be invited to delete all of us.
This would make someone at VRBO very happy.
