The 45 AU is the maximum radius of the object, not the precision of
any singularity.  They know the center of mass of the object (the
singularity, if there is one) to better than that, just from S14's orbit.

Regardless, the defining characteristic of a black hole is having an
event horizon, not a singularity.  Who knows, perhaps there is physics,
unknown to us, that prevents formation of a singularity in a black hole.
Doesn't matter, as long as there is an event horizon, it's a black hole.
