Gavra, no, I don’t mean it’s literally amira l’akum, I just mean that it could be assur despite that it’s dibbur. I think you would need to provide a source to be mattir grama al y’dei dibbur.
Aderabba, that is why I started with the point that Dibbur is not a Maase all over shas. Therefore, there is no reason to think that Grama even begins to come into play for a non-Maase!! (L’cheorah) Amriah L’Akum requires its own Gezairah for a reason.
P.S. This specifically comes up by Shabbos, where a Melacha is required. Elsewhere (such as Adam HaMazik), “Kocho” is enough to be a mechayiv, and I would argue (first thought) that if you command your robot to break someone’s car, that would be Adam HaMazik (vs. Memono).
(Of course there is a semi-serious issue of Mizto Chefticha V’daber Davar, but there are ways around that as well, as is well documented elsewhere in poskim).
