Preheat the oven to 350 degrees F.
Add 1 tablespoon olive oil to a skillet over low heat. Stir in the garlic and onions. Cook 1 minute. Add the rice, stirring to coat with oil, about 2 minutes. When the rice has taken on a pale golden color, pour in the white wine, stirring constantly until the wine is fully absorbed, and then add a dash of salt. Add 1/2 cup broth to the rice, and stir until the broth is absorbed. Continue adding the broth 1/2 cup at a time, stirring continuously, until the liquid is absorbed and the rice is al dente, 15 to 17 minutes. Stir in the Parmesan and mascarpone. Finish with the black truffle oil, salt and pepper to taste.
In a frying pan, add 1/4 cup vanilla-infused olive oil, the 2 whole garlic cloves and the thyme and heat for 1 to 2 minutes over medium heat. Place the lobster tails in the pan flesh-side down and sear until golden brown, about 2 minutes. Flip over and spoon some infused oil onto the lobster tails. Place the pan into the oven and cook for 2 minutes.
Once cooked, remove the lobster tails from the pan and place the pan back on the stovetop. On low heat, add the remaining 1 tablespoon vanilla-infused olive oil and diced tomatoes. Remove the seeds from the vanilla bean and mix the seeds into the tomato and oil mixture.
Take the shrimp and remove the tails. Once the tails are removed, add them into the pan for 3 to 4 minutes, turning occasionally until cooked.
Spoon the risotto onto plates and place the lobster tails onto the risotto. Place the shrimp on the risotto and spoon the tomato mixture on top of the risotto. Once plated, cut the lime in half and serve with half a lime on each plate. Drizzle more vanilla-infused olive oil on and around each plate and serve.
