Well shouldn't you believe and trust Tsongkapa more than Trijang Rinpoche?
The person who banned Dorje Shugden is His Holiness the Dalai Lama. So, it is HHDL along with unenlightened Nechung, that ban Dorje Shugden and first referred to Him as Dhogyal.
So your question should be, why pick His Holiness the Dalai Lama over Trijang Rinpoche's advice? Tsongkhapa did not ban Dorje Shugden.

How many of you have met Trijang Rinpoche? None right? Unless you are 80 years old. Trijang Rinpoche is your lineage guru and you should trust? Well so is Tsongkapa. Tsongkapa is your lineage guru also. Why choose Trijang over Tsongkapa? Illogical bias?
I have not met Tsongkhapa, nor have I met Trijang Rinpoche. Both are enlightened beings, how can I choose one to be right over the other. I choose Dorje Shugden because my Guru trusts him, and he kindly gave me His practice.
So if I needed to pick, the question to myself would be, "Is His Holiness the Dalai Lama correct, or my Guru?"

Dhogyal is not applicable practice to Gelugs or anyone. Since you place faith in these 'deities' or deities by virtue of your faith in certain lamas' words, why pick some lamas over Tsongkapa?
Dorje Shugden is the emanation of Manjushri. It was Manjushri who blessed Lama Tsongkhapa with the ability to recall all of his previous lives, it was Manjushri whom Lama Tsongkhapa had visions of and could communicate with directly with and it was Manjushri's teachings which Lama Tsongkhapa studied.
So really, if I believe in Dorje Shugden, I trust Tsongkhapa.

Stop Dhogyal and pick up with Kalarupa, Mahakala and Vaishrava as they have zero controversies-ALL ACCEPT THEY ARE ENLIGHTENED.
We don't have to trust what everyone accepts is right. If that's the case why even study the Dharma, most of the world does not accept it as a religion.
