I'm not even sure why they are doing such an elliptical orbit like
that?
Any advantages for viewing angles or stuff like that?

No ****ing idea.

The distance isn't enough to alter the view seen, but it _might_ be
enough to play VLBI games but I don't believe the orbital information
and transmission setup is precise enough to preserve phase/timing
information down to the nanosecond.

I was thinking maybe the orbit would allow it to avoid the day side of
the planet and avoid being blocked by the planet as it looks at distant
stars. Also avoid it'll the radio noise of the planet. Earth is
supposedly much brighter than the Sun when it comes to radio.

Orbits are not accidental so either they wanted it to be there, or a
higher purpose was served that has putting it there as a byproduct. I
just can't figure it out.

Maybe they don't have a strong enough booster to put it in a circular
orbit that far up? That's almost as far as the Moon.
