Can you provide this statistic?
I'm a facial surgeon and have dealt with lots of facial dog bites over the years and can't think of a single one caused by a Lab/Golden retriever. Obviously they may bite but I don't believe they cause "more damage"
I'm only seeing bites that need surgical closure, but Ive seen lots of bully bites including staffies, lots of German shepherd. A few Jack russels/daschunds/chihuahuas (although all these are small and quick). Huskies, cane corso. No labs/GR that I can recall.
The difference between a daschund bite say and a potential Xl bully bite is humungous. Bigger dogs cause more damage. Theres a massive difference between a small nip and a bite from a large/powerful breed. We aren't seeing deaths from labradors
