Students using AI assistants and the professors who have to keep up

I was glancing through a bibliography of a medieval monastic reform movement (Cistercian Reform) and clicked on something that offered help from "Leo AI." Wondering who or what that was, I found I could have a chat with Brave Leo--for a price:

"Chat Privately with Brave Leo

Brave Leo is a private AI smart assistant that enhances your use of the web. Leo is free to use with limited access. Brave Leo Premium offers more models, higher limits and gives subscribers early access to new features. The default model will change from time to time. See the Brave Help Center for more details.

By default, when you ask Leo a question about a website or page you are viewing, the content of the webpage you are viewing or any text you highlight on a page, as well as your search query will be sent to Brave servers in order for Leo to provide a response. In some cases, Leo will send queries derived from your input to Brave Search and use the search results to better answer your question. Brave does not guarantee the accuracy of responses, and responses may include inaccurate, misleading, or false information. Don't submit sensitive or private information to Brave Leo, and use caution with any answers related to health, finance, personal safety, or similar. You can adjust Leo’s options in Settings any time. Go to Settings > Leo.

Leo does not collect identifiers such as your IP address that can be linked to you. We do not train our models based on your data, including your search queries or Brave Leo’s responses. No personal data is stored on our servers, or retained by Brave. See the privacy policy for more information."

Then I was supposed to click on "I understand." But I don't. So, I didn't. How does a college professor of some age ever evaluate a paper of a student who had help from Brave Leo?
