I was under the impression you got a 60 day grace on the TN as well: https://www.ecfr.gov/current/title-8/chapter-I/subchapter-B/...

"An alien admitted or otherwise provided status in E-1, E-2, E-3, H-1B, H-1B1, L-1, O-1 or TN classification and his or her dependents shall not be considered to have failed to maintain nonimmigrant status solely on the basis of a cessation of the employment on which the alien's classification was based, for up to 60 consecutive days or until the end of the authorized validity period, whichever is shorter, once during each authorized validity period. DHS may eliminate or shorten this 60-day period as a matter of discretion. Unless otherwise authorized under 8 CFR 274a.12, the alien may not work during such a period."

This is also what I've been told by my company's lawyers.

This is correct and what I've been told by border agents as well.
