You’re right, it’s Genesis 49:10,and yes SHILOH is the Messiah so there IS something in genesis that refers to Messiah. Not only that but there is at least one other prophecy in Genesis about Messiah:
He will strike your head, and you will strike his heel Gen 3:15.
The scepter shall not depart from Judah,
Nor the rulers staff from between his feet,
***The scepter departed from Judah when the Romans conquered it, and the ruler’s staff at the same time. Judah lost self determination at that time, which is about the time that Jesus was born... per God’s plan.
