Preheat the oven to 375°F and lightly grease an 8x8 baking dish.
In a large bowl, beat the dairy free cream cheese, mayonnaise, buffalo hot sauce, lemon juice, dill, garlic powder, and onion powder until smooth and creamy.
Fold in the shredded chicken and half of the dairy free cheddar until evenly coated.
Spread the mixture into the baking dish and sprinkle the remaining cheddar over the top.
Bake for 20 minutes until hot and bubbling around the edges. For a golden top, broil for 1-2 minutes, watching closely.
Sprinkle with green onions and serve warm with celery sticks and tortilla chips.
