The Tleitylwesi Bubble covers just a shade over 90% of the sphere surrounding their system's stars (a close binary system)

This means that any waste heat that is not irradiated from the outside of the bubble escapes through the remaining 10% of uncovered system. This would be detectable, although with some difficulty. Unless a significant fraction of the luminosity of the star is stored in the ingenious black hole pairs.

The Tleitylwesi are, for all intents and purposes, invisible to Terragens and, more importantly (to them) from any extant civilizations in the "Sandbox Volume" due to distance (54,622 LY from Sol and 83244 LY from the nearest starflight-capable civilization in the sandbox) and to their location in the Milky Way's "observation shadow." Aside from the heat signature becoming indistinguishable from background noise, the blocking of 90% of the system's visual emissions means it is invisible to optical detection as well.

In any case, any remote detection of the Tleitylwesi civilization would, in the absence of corroborating communication or contact, lead to a classification as a low or even null technology society, which leads back to the original query.
