I was wondering about it as well, once I reread the story I noticed:
"In Primordial Greece before the fall of the Minoan civilization. The head God Zeus was shown as the eternally young God called Korios. He was blue colored had a White bull, 12 cow herder companions and a consort called Rodha. He played a sacred flute as well. Korios is from the Sanskrit, Kumara."
The number 12 reminded me of the zodiac and I think it's clear the white bull represents the sign and/or age of taurus.
It also represents venus the planet of that sign, and it is white because:
"Venus in Sanatana Dharma is the highest cosmic principal it rules sound and white light and the spectrum of light. As it descends creating all existence which is condensed sound and light. However what we perceive as white light is stated in the Vedic texts to be blue light. This is why the ancient image of the God Sanat Kumara are also shown blue. The purified soul and the concept of Venus."
So, possibly the bull is white to represent our perception of light instead of how it actually is in it's pure form(blue). As a material manifestation of Sanat Kumara this makes sense as it is diluted or a fraction of something bigger.
Also, during the last age of taurus it seems the bull was part of a few myths:
Ptah from egypt had Apis the bull as a manifestation and symbol of pharoahs.
Sumer had gugalanna slain by Gilgamesh as the sun and Enkidu to represent the disappearance of the constellation during the spring equinox..
In a way it could also symbolize being reborn as you suggested:
"This symbol of Venus would have 666 placed with it to show spiritual rebirth. Venus's number also connect to the sun. The ankh the symbol of spiritual rebirth is the symbol of Venus.
Venus rules the mystical transformation of the soul as the morning and evening star. Venus's eight year cycle is a spiritual number of enlightenment and immortality. Its position on the horizon as the evening star just before it disappears into the night of the underworld, to its triumphant reappearance in the dawn heralding the reborn soul, spiritual victory."
I think that myths and their symbols have a dual purpose. There is a factual event it is relaying either directly or through various symbols and there is also a personal interpretation for those who read them. Kind of like how dream symbols vary depending on a persons experience with them.
