Yes, there certainly are written teshuvos by them and earlier poskim.
Even when Sir Montefiore ascended to the Har Habayis in the late 1800s, the gedolim of Yerushalayim publicly denounced him the following Shabbos in Shul. He tearfully and publicly apologized to the rabbonom saying he hadn’t realized it was assur and promising never to do so again, and the rabbonim said he was forgiven. And he was one of the most powerful figures and wealthy Jewish benefactors of Eretz Yisroel of the time. This is hardly anything new or “political”, as you attempt to malign the gedolei yisroel and poskim of our dor.
