Jesus in every passage in the OT? That’s forcing it. Much of the OT is specific to that moment in the past.
Does the OT anticipate Christ throughout? Yes. But we’re imposing our presuppositions when we try to see Jesus in the story of Samson and Delilah, for instance.
The story of Samson is primarily a human illustration to us of God's redemption grace not unlike the wandering prodigal son. Though Samson squandered his gifts, in the end he "came to his senses" and came back to do God's will in a might way. Delilah, like Balaam, failed in trying to thwart God's plan. The parables that Christ often gave, in many cases can be found in living examples in the Old Testament. And they all point to Him.
BTW-This is only a tip of Christ working in Samson's life. These illustrations are often like an onion in which one can peel layer upon layer.
