Dietary cholesterol is transported to extrahepatic tissue by
LDL

It is worth noting that dietary cholesterol is not directly transported to extrahepatic tissues.
Though the major function of chylomicrons is to transport exogenous triglyceride to various tissues, it also transports the other dietary lipids (including cholesterol) to the liver after conversion into chylomicron remnants.
In the liver, this dietary cholesterol and the endogenous cholesterol which is synthesized in the liver itself are incorporated into VLDL which is secreted into the circulation. In circulation, VLDL is converted to IDL and then to LDL. This LDL serves to deliver the cholesterol to various extrahepatic tissues. Thus, LDL transport dietary as well as endogenous cholesterol to extrahepatic tissues.
