To get damages she would need to demonstrate harm. But if she could, this becomes interesting, as Google can not hide behind the usual search-engine defense: they are not merely linking to sites here, but making up their own facts. (IANAL.)

I think Google would be fine in this case, if we're assuming American law. Wilentz arguably qualifies as a "public figure" and so Google would have to be proven to show gross negligence and/or malicious intent in getting the dates wrong. Assuming the googlebot did as it normally does, Google has an even stronger case that they aren't intentionally being bad actors, as the googlebot gets so many other things correct with its algorithm.
