I think the riskier chemicals that might be included in a chemistry kit aren't today because of the potential for lawsuits. It's also probably a lot cheaper to produce a chemistry kit with non-toxic chemicals.
The US government doesn't care much about the chemicals that might be reasonably used for chemistry experiments. The DEA watchlist is pretty specific and I don't believe the DHS/FBI/ATF are going after people buying small quantities of chemicals that have legitimate uses.
