I think that the reduction in lead is far too late, if you figure that it's cumulative exposure over someone's lifetime, not short-term (which I have not looked up, but would expect to be the case).
googles to sanity check

Yeah, so it's a childhood thing. You'd be talking about on the order of maybe a 20 year delay until a reduction in exposure translates into peak potential serial killer period.
Also, for stuff like lead paint, it's gonna be around for decades, gets kicked up over time, so it takes an even longer time for regulations to go have an effect, and that effect is very spread out, whereas this is a pretty sharp increase and decrease.

I'd -- without digging up numbers -- guess that halting leaded gasoline probably had the most-immediate impact on lead in the air, since burning leaded gasoline is gonna put it straight into the air.

If something were gonna happen in the 1970s to reduce the rate of serial killing, to be a relevant input, it'd have to be something that had a major immediate effect rather than a long-term developmental effect.
And leaded gasoline and leaded diesel and leaded aviation fuel and lead pipes in household plumbing. Probably lead in the cigarettes everyone smoked literally everywhere.
