@[email protected] Why not just use ceramic bowls or trays? They have no nasty chemicals and they're eco-friendly, dishwasher safe, versatile (can be used in a microwave too, and also double up as serving trays), and conduct heat reasonably well unlike silicone trays.
A good quality one shouldn’t affect it. I don’t have an air fryer but use silicone mats in my oven. Low quality ones will affect taste and smell a bit but good ones don’t mess with food at all
