Slice each eggplant lengthwise into ½-inch thick planks (you should have 12 planks). Trim rounded surface from each end piece so it lies flat.
Adjust 1 oven rack to lower-middle position and second rack 8 inches from broiler element. Heat oven to 375 degrees. Line 2 rimmed baking sheets with parchment paper and spray with vegetable oil spray.
Arrange eggplant slices in single layer on prepared sheets. Brush 1 side of eggplant slices with 2½ tablespoons oil and sprinkle with ¼ teaspoon salt and ¼ teaspoon pepper. Flip eggplant slices and brush with 2½ tablespoons oil and sprinkle with ¼ teaspoon salt and ¼ teaspoon pepper. Bake until tender and lightly browned, 30 to 35 minutes, switching and rotating sheets halfway through baking. Let cool for 5 minutes. Using thin spatula, flip each slice. Heat broiler.
While eggplant cooks, heat remaining 1 tablespoon oil in 12-inch broiler-safe skillet over medium-low heat until just shimmering. Add garlic, oregano, pepper flakes, and ¼ teaspoon salt and cook, stirring occasionally, until fragrant, about 30 seconds. Stir in tomatoes and their juice. Increase heat to high and bring to simmer. Reduce heat to medium-low and simmer until thickened, about 15 minutes. Cover and set aside.
Pulse bread in food processor until finely ground, 10 to 15 pulses. Combine bread crumbs, ricotta, ½ cup Pecorino, ¼ cup basil, lemon juice, and ¼ teaspoon salt in bowl. With widest ends of eggplant slices facing you, evenly distribute ricotta mixture on bottom third of each slice. Gently roll up each eggplant slice and place seam side down in tomato sauce.
Bring sauce to simmer over medium heat. Simmer for 5 minutes. Transfer skillet to oven and broil until eggplant is well browned and cheese Is warmed through, 5 to 10 minutes.
Sprinkle with remaining ¼ cup Pecorino and let stand for 5 minutes. Sprinkle with remaining 1 tablespoon basil and serve.
