The Torah does not deny the possibility of a Triune God.
The Jewish Kabbalah goes further

The Jewish mystical doctrine known as “Kabbalah” (=”Tradition”) is distinguished by its theory of ten creative forces that intervene between the infinite, unknowable God (”Ein Sof”) and our created world.
Through these powers God created and rules the universe, and it is by influencing them that humans cause God to send to Earth forces of compassion or severe judgment.
A truckload of made up nonsense. As far as Judaism is concerned, there is ONE G-d, only one. This is declared on virtually every page of our prayerbook. Only people claiming otherwise are messyonics, who spew lie after lie after lie. I don't give a flying fig if you flame me, this is what's true. Judaism = one G-d. Other religions of any kind = however many deities they want.
“The Torah does not deny the possibility of a Triune God.”
Yes, it does!
Have you ever read the Shema?
שְׁמַע יִשְׂרָאֵל יְהוָה אֱלֹהֵינוּ יְהוָה אֶחָֽד
Shema Yisrael. Adonai Elohenu, Adonai echad!
Listen, Israel. The Lord is our God, the Lord is one!
-Devarim (Deuteronomy) 6:4
The rabbis from Moses onward have always defined God as indivisible and not physical much to the anger of civilizations 3000 years ago to the present. Many Jews have died at the hands of the nations for not compromising that basic tenet of the nature of God. The closest he gets is Spirit. He is beyond space and time.
Even the Christian’s New Testament points this out.
“God is spirit, and those who worship him must worship in spirit and truth.”
- John 4:24
It doesn’t mention anything about Him being physical or divisible.
Yes, the Torah could not make it clearer that there is one, indivisible God. Judaism does not believe that the creator and master of he universe operates using split-shifts. Such a notion is anathema to Judaism. You can poke around and look for foreshadowing as one might do in a literature graduate seminar, but that does not make it so.
