The whole "order versus chaos" theme seemed a bit shallow for such old and advanced civilizations, and probably overlooked some important background motivations for the clash of cultures among the First Ones.
Part of the point is that it is
shallow. The other First Ones have no interest in the battle, except
that the Shadows (and later the Vorlons) used it as an excuse for genocide, at which point they intervened, over and over. The Vorlons and the Shadows themselves mature when they are forced to recognize the pointlessness of their actions by the younger races, and joined the extragalactic community.
My thought is that after the Thirdspace incursion, the Vorlons experienced a massive culture shock, and became extremely cautious and conservative compared to their previous trajectory, and avoided uses of certain new technologies they began to suspect were risky.
Unfounded supposition, really. We have no idea what technologies they're willing to use or not.
They may have then been more keen on controlling the development of all cultures in their vicinity in order to prevent rogue redevelopment of technologies such as the gateway that could potentially annihilate them and other species in the galaxy.
There's no evidence that any Younger Race could even begin to comprehend how to make such a thing. That's certainly not likely compared to their simply having failed in their mission to protect and guide the Younger Races.
Nevertheless, it seems that they never wanted to admit what happened to the Shadows, either for fear of losing face in the estimation of First Ones society, or possibly alerting the Shadows to something they might be tempted to exploit themselves.
The abovementioned RPG states that the Shadows were aware of the Thirdspace alien invasion, and with the other First Ones, aided the Vorlons in destroying the invaders, and smashing all gateways save those that were cast into hyperspace by the invaders' thralls. The Shadows have no interest in being enslaved, or all the younger races being enslaved, nor, as said in Into the Fire
do they even want to actually kill the Vorlons.
