I have a question (nothing urgent)

Is there any guarantee that when NOSYS is 1, LWIP will not make any
attempt to use or reference thread local storage (My bare metal system
currently doesn't support it).

lwIP itself cannot use thread local storage. The port must supply this if used. However, it is only used with LWIP_NETCONN_SEM_PER_THREAD for now and this is not used with the callback API available for NOSYS. So for NOSYS, you're safe.
