Catholic websites and sermons are overflowing with "prayers for Ukraine"...but no "prayers for the conversion of Russia."
I am old enough to remember when prayers for the conversion of Russia were said at the end of every Low Mass after the St. Michael Prayer. Collectively known as the Leonine prayers or "prayers after Mass."
I also remember every family rosary, in my youth, including "for the conversion of Russia" in the intentions.
In 1965, hot on the heels of Vatican II, the Church officially suppressed the "prayers after the Mass" and the prayers for the conversion of Russia. Some thought it was because we didn't want to make the communists mad at us.
