Something I've always wondered about were Tesla coils. When I was a

ozone that we all had to leave for a couple of hours with the windows
wide opened to air out the house. Would that much ozone have killed
surface bacteria as a germicidal lamp would have?

It takes a LOT. Once that level is reached, however, the killing does not take a huge amount of time. And ozone concentrations will vary by the amount diffused and the amount generated as it is very short-lived.
