In the Northwest Mansion episode, Pacifica is the last person before the llama painting is revealed. Given the other items in that room, it is out of place. This points at Pacifica being the llama. Especially when the other references to llama's so far (as I recall at least), are the llama sweater on Mabel and Larry King's head talking about it. If Mabel is the shooting star, (as alluded to by Bill), I think we can rule out Larry King's head, that whole scene can be discounted as a llama icon on the Bill Cipher Wheel reference. Several other GF boards/communities/posters all but agree this is a done deal, but the edits were removed as "speculation". I challenge that. I would like to hear the evidence on why people don't think she is the llama. Especially given Dipper's possible relationship change with Pacifica, I think it points further to her being the llama.
