Berlanti Productions not being involved with this Naomi series carries greater weight than some people seem to want to acknowledge because of one simple fact: the company has been involved with the production and/or development of every comics-based television series aired on The CW with the exception of iZombie.
The fact that this Naomi series is being developed for The CW and the character's connection to Superman are not strong enough evidence to support the notion that the establishment of a connection to the Arrowverse through the inclusion of Tyler Hoechlin's version of Superman is inevitable, especially in the face of the aforementioned notability of Berlanti Productions not being involved with its production and development.
