No, LDL doesn't "change it's behavior". That's not a real thing.
That hypothesis is not based on evidence. The vast majority of the early human population lived around the equator and ate a predominantly plant based diet. The claim that they had "almost zero heart disease" is also false. A study on mummies from around the world show an atherosclerosis incidence of around 34%, regardless of location.
Also, seed oils reduce inflammation, reduce LDL and result in lower incidence of high blood pressure, insulin resistance, heart attacks, all-cause mortality and so on when compared to butter.

Background Increasing evidence highlights healthy dietary patterns and links daily cooking oil intake with chronic diseases including cardiovascular disease (CVD) and diabetes. However, food-based evidence supporting the consumption of cooking oils in relation to total and cardiometabolic...

Conclusions: In our large community-based study, we observed weak but statistically significant
inverse associations between several types of inflammatory biomarkers with RBC n-6 PUFAs. Our findings do not support the hypothesis that omega-6 fatty acids are pro-inflammatory.
we found an
inverse relationship between n-3 fatty acids, EPA and DHA, and MUFA with hs-CRP concentration in CAD patients. Our finding suggests that SFA (saturated fatty acid) was
directly related to plasma IL-6 and hs-CRP levels.
Atherosclerosis, with its major manifestation, coronary artery disease (CAD) is a chronic inflammatory disease. Dietary fatty acids intakes favorably effect on inflammatory responses. This study was conducted to examine the association between ...
