That's not what entrapment is. She had every chance to walk away, and on multiple occasions willfully ignored the answers to her questions about the source of the property.

Police are very good at avoiding entrapment, and this woman knowingly committed a crime. An example of actual entrapment would involve the undercover agent threatening to commit violence or even to report her to authorities unless she went through with the deal.
