Grilling kale gives it a toasty flavor; the smartest way to prepare kale for grilling is blanching it so it becomes tender and doesn’t burn.
In a large pot of boiling salted water, blanch the kale until it is just tender, about 3 minutes. Drain and lightly squeeze out the excess water. Blot the kale dry and transfer to a bowl. Add the vegetable oil, garlic and chile, season with salt and pepper and toss well to coat.
In a skillet, cook the bacon over moderate heat, stirring, until crisp, 5 minutes. Drain on paper towels.
Light a grill. Place a 10-inch springform ring (not the bottom) on the grill to contain the kale. Carefully pat the kale inside the ring, pressing down to form an even layer. Grill until lightly charred on the bottom, 3 minutes. With tongs, turn the kale over and grill on the other side for 3 minutes. Alternatively, grill the kale on a perforated grill pan, tossing occasionally.
Transfer the kale to a bowl and immediately toss with the bacon, olive oil, lemon zest and lemon juice; season with salt. Serve right away.
Seems like you might want to grill the bacon since your using the grill for the kale. I'm also going to forgo the springform pan as it seems superfluous.
