Yes I know hoarseness has to do with her vocal chords certainly due to a lack of rest but if she was constantly adjusting her ear monitors it means she has difficulties to hear her voice and it didn’t helped to stay on pitch I think.

Yeah, very likely, but it also could be that they just didn't fit comfortably/were falling out (I'm not entirely sure it's possible though, since they're custom made).
Singers usually make signals to their technicians to increase or lower the volume, but I don't remember Ayu ever doing this, which is kinda weird.
