This is ridiculous. Customer usually expect or assume analysis would be accurate enough. In addition, on some cases customer have no way to verify whether the analysis result is accurate or not.

Such softwares used for tracing addresses only instigate stress on a victim that got scammed or lost their coin.
It's not the only reason to use blockchain analytic service though. For example, many such service claim their service is useful to help comply with law.
