This isn't quite accurate, dietary interventions can have huge impact on LDL.

Seed Oils (Industrial oils from processing plant seeds, or vegetable oils) - are known to dramatically lower LDL... Oreo Cookie Treatment Lowers LDL Cholesterol More Than High-Intensity Statin therapy in a Lean Mass Hyper-Responder on a Ketogenic Diet: A Curious Crossover Experiment

Ketogenic ABF Can increase LDL from the population average considerably in a few months

A long term standard western diet can increase LDL through glycation and oxidation damage to circulating LDL, preventing the liver from reusing that LDL and producing more LDL (so there is a build up of usable LDL and damaged LDL showing up as elevated LDL)

All that being said, LDL, and more generally Cholesterol - IS NOT A DISEASE. You would die if you didn't have any, the body will produce it on demand if its not consumed in the diet. The link between LDL (undamaged) and heart disease (the lipid heart hypothesis) is not based on repeatable science, and isn't holding up with modern scrutiny
