“The Noda B’Yehuda says shituf is pure Avoda Zora for goyim. “
The Noda B’Yehuda is entitled to his opinion, but he is paskening against Rashi, Tosafot, HaMeiri, and the Rema.
In any case, indirect support of A”Z is extensively discussed in the talmud tractate of that name that we just finished in the Daf Yomi. I’m not a posek (!) but there is certainly room for a posek to find ways to be meikel in the situation described, particularly based on the comments of the rishonim I just mentioned. CYLOR.
