https://www.academia.edu/30226534/The_Identity_of_the_Standing_Figures_on_Pithos_A_from_Kuntillet_%CA%BFAjrud_A_Reassessment this also talks about the figures

It seems like one of the articles that this Chatbot referenced was https://www.thegospelcoalition.org/themelios/review/did-god-have-a-wife/ , a review on a book written by William Dever about wether or not God had a wife. The Chatbot seems to forget though, at the bottom of the review, the author gives contrasting information and disagreements with Dever's argument. Notably this quote I have attached here. "While archaeological data does testify that, at various points in its history, ancient Israel largely failed to be monolatrous or monotheistic, this is in accord with the biblical text.Thus, Israel did not have a polytheistic history in the sense that it embraced polytheism as one stage in its religious evolution. We should not confuse the history of Israel’s failures with the history of monotheism."

2 Kings 21:6 mentions that King Manasseh, did "much evil in the sight of the LORD, provoking him to anger"

It does say this yes, however how I am reading this passage in context, the portrait of Asherah is a portrait of a foreign god, because the King had been placing portraits and idols in the temple which was upsetting a lot of people.
