Okay, I was thinking that was the case since I couldn't find her anywhere, though the text is misleading. It wasn't the chapter hint though, it was some text on the page. After the meeting with Lazren and Avery, on the page where the Current Goal changes from "Meet & Greet Avery" to "Wait For... Something," part of the text says: "Maybe you could check in with Lazren — or catch Avery for a few more questions — after you did your morning rounds and had some time to organize your thoughts," which makes it sound like Lazren would be available to talk to.
