You are highly sensitive to lemon, that's all. The topnotes are not shrill. Guerlains tend to be smooth by nature. And Creeds tend be be very natural in their notes. For example, there is a Lemon-based creed called BOIS DE CEDRAT, which is almost pure lemon. But it is never shrill. I am not saying that shrill citric topnotes do not exist. I am just saying that these two perfumes are not very sharp.
