Yes, you can catch the shiny version of Phantump in Pokemon GO, after it was added to the game in the 2023 Halloween event.
Any Phantump you encounter in Pokemon GO has a very low chance of being shiny, whether you find one in the wild or encounter it as a reward for completing Research.

Phantump Shiny Odds in Pokemon GO
The odds of Phantump being shiny are 0.2%. This means that just 1 in every 500 Phantump is the rare shiny version.
Unfortunately, there is no way of increasing Phantump’s shiny rate, so you’ll have to settle with finding one roughly every 500 encounters!
