Torah Temimah points to Toras Kohanim (Sifra), Vayikra Dibbura DeNedavah, on 1:9 (reiach nichoach la-Hashem — Name only).
Sefaria — Sifra / Toras Kohanim, Vayikra Dibbura DeNedavah
English: It was taught, Rabbi Shimon ben Azzai said: Come and see what is written in the section of offerings — that there is said of them neither “El” nor “Elohim,” but only Hashem, so as not to give an opening to a disputant to divide [the Name].
Observation of exclusive Tetragrammaton in the korban section.
Offerings are dedicated only to the unique Name, leaving no textual foothold for attributing them to other divine designations. The consistent “la-Hashem” of the korban section is intentional closure against dispute.
