I've designed a logging system designed to address some of these issues (https://eliot.readthedocs.io/en/1.2.0/) and I know people have e.g. used the trace ID it provides to correlate Sentry errors with logging traces. Not a full solution, obviously, but if you do go this route do borrow some ideas if it's helpful.

As far as a business goes: it's a real problem. Whether people will pay for it, that's something else. You may wish to spend some time reading up on questions real people ask about these systems (e.g. on relevant forums) to see what patterns you notice. https://stackingthebricks.com/vintage-sales-safari-in-action... and other articles there have some examples of doing this sort of research.
