Responsa for Avodah Zarah 12:1

Nevertheless, it seems that it would be forbidden for a Jew to sacrifice their paschal lamb, because this is an established commandment for them, and we do not leave Noahides to add on to their seven commandments. For it is stated in the chapter “Arba Mitot” (Sanhedrin 58b): “A Noahide who observes Shabbat is liable for death.” The same applies to any other commandment, as Maimonides wrote in the Laws of Kings (10:9). If so, how can a Jew slaughter on their behalf? He must prevent them! Indeed, the Sages stated (Avoda Zara 6b): “It is forbidden to hand to a Noahide a limb from a living animal; even though one does not transgress “placing a stumbling block before the blind” unless they are standing on opposite sides of the river, as noted in the first chapter of Avoda Zara (ibid.), it is nevertheless forbidden to aid them, for indeed there is a duty to separate them [from the violation]. Tosafot stated similarly in the first chapter of Shabbat. And if this lamb is akin to the paschal offering, a commemoration of the Akeida, then it is indeed a sacrifice. Non-Jews may offer sacrifices on their altars as long as it is not a fixed commandment. Therefore, if a Jew slaughters it, he is slaughtering sacred property outside the Temple precincts, and thereby incurs the punishment of extirpation (karet), even if the sacred property is the offering of a gentile. Similarly, one who eats from it is eating from sacred property outside of the Temple precincts.
