If it works like on Socialblade, a drop in views usually indicates video delistings (potentially due to copyright claims as she runs a "reaction" channel). Detection of view botting is usually punished a lot more harshly with whole channel demonetization, which I'd be surprised if any big creator were to risk that.
Even if it were view botting, in those cases they rarely reverses payments AFAIK (as that would mean them having to pay back advertisers and losing out on revenue).
