okay, so we now have: parent/homeowner responsible if someone drives home drunk, parent responsible if child gets drunk via abuse/neglect laws, and parent responsible for other crimes and damages caused by a child via dozens of individual laws.
is that enough examples to satisfy your initial request?
(which was a request for examples of the extremely broad statement: "We used to hold parents liable.")
So I asked for examples because there is a large difference between "We used to hold parents liable" meaning "we used to, socially, hold parents accountable for raising well adjusted humans" (which I would mostly disagree with) vs. "we used to persecute parents for normative laws" (which I mostly agree with).
I know your point is talking about point 2, but I believe OPs comment was about point 1. But I also still don't know what the "used to" means in the original, do we not anymore?
