Congrats on your class!
Is the oil 'bad'? Not at all.
Extra virgin oil has too low a smoking point, so your instructor had you brown the meat in regular oil. There is a thread of ours out there somewhere describing the molecular destruction that occurs to EV oil when it gets too hot. As it breaks down, its health benefits go up in smoke, literally.
Any version of olive oil will be equally good for you, be it regular or 'lite', virgin, extra-virgin, or even the rare extra-extra-virgin.
(Bonus Question: How do they make 'extra-extra-virgin' olive oil?)
But it's better to use plain olive oil for browning and saute-ing, as it can take more heat. Peanut oil is great with high heat too. But I would never recommend any kind of generic vegetable or 'canola' oil, (your teacher's "cooking oil") which is squeezed out of who knows what seeds and is sometimes hydrogenated. Stick with the known.
The ratio of 2 T of oil to 5 chicken breasts is like, what, 18 F max to 20 P or so. But most of that oil will stay in the pan. While there will remain a trace of oil on the cooked chicken, I wouldn't "count" the 1 to 2 spoons of oil you start with as Zone Fat blocks; I would count it, maybe, as 1 block (1/3 teaspoon)
per serving, and then add fresh EV oil (or sesame or almond oil or some other tasty dietary fat) to the finished dish.
Remember that small additions of mono-fat are 'neutral' blocks, will keep you feeling full longer, and add flavor. And what, we ask, is life without flavor?
When are sharing the recipe?
