Could it potentially be an object orbiting around the cosmic center that just so happens to have an orbital path that crosses us?
I have to admit that astronomy is what caused me to change majors, but that’s because I stopped going to class when the lesson was, “This is a terrestrial planet, it’s rocky,” and my first exam was like, “If it’s 5:45pm in Tanzina on October 15th, how many degrees is the moon above the horizon?”
Since the speed something is moving away is dependent on the distance, something billions of light years away is absolutely not going to be moving towards us, regardless of its local orbits.
If it’s blue shifting from that distance, then it’s likely some advanced technology is moving it in our direction.
There’s not many other explanations for that.

Had to do AM because it’s below the horizon in the PM.
I really want you to know that I appreciate this.

Let’s suppose that for some reason it’s completely normal, and it’s just simply speeding toward us.
OP says it’s billions of light years away. Doesn’t that mean that we still have a few billion years?
Since they didn’t note extreme blue shift, probably several billions of years
