I'm pretty sure she's not shading anyone. I think the "that" she was referring to when she said what she did was the YG-SM competition in regards to her vs Kyuhyun being considered part of it. It wouldn't make sense of her not to know about the song itself but listen to her song on a consistent basis. She obviously holds her seniors in the industry in high regards so it would make more sense of her to be doing that if she was worried about losing to him. You don't have to be Lee Hi biased to see that...
