This is highly interesting but I'm confused. Do you mean that diet doesn't matter when it comes to blood cholesterol
and the LDL/HDL ratio can only be affected by medication or that only the ratio but not overall blood cholesterol can be influenced by the diet?

Diet matters a lot. Apparently, it has been shown that for some people, milk fat in the diet correlates strongly with serum (blood) levels of cholesterol.
However, the effect of cholesterol in your diet seems to have little to no effect on your serum levels.
Serum cholesterol is actually pretty important: It is the precursor to Vitamin D (the other ingredient being sunlight exposure). For sure, it is an indicator of trouble, but it is unclear if it actually causes trouble itself or is part of the body's attempt to make things right.
Statins reduce cholesterol, and reduce the incidence of heart attacks, but they either increase or do not affect all-cause mortality (depending on which study you look at).
The science is far from settled on this, despite what most medical professionals would have you believe.
