Even if you want to be skeptical of the PBI, I'd think the Jewish Community of Rome and the Yad Vashem Holocaust Museum would do their due diligence to confirm this info matches other information they have about the area at the time before joining a press release about it?
I know that certain actions of certain people, or history can shed shadow for institution, but I am not convinced about how "good" have Church done, and how much "bad". It would be not easily quantifiable. It should not be also dependent on contemporary perception.
I am not sure if using world war 2 history does the topic justice. We look on it through rose tainted glasses of today. We do not know how it was. For example if you did not participate in it you could be in danger yourself. Please take a look at Franz Jägerstätter biography. For not taking Hitlers oath he was sentenced to death.
