OCR based invoice recognition has been a solved problem for well over a decade. Source: I've consulted for a company doing that. No exploitation. No LLMs. Just clever engineering.

In my neck of the woods, B2B invoices are now required to be delivered over the Peppol network in UBL format, which further improves reliability.

Doesn't necessarily eliminate the need for an accountant, because the chosen UBL standard has lots of room for interpretation and ambiguity, and it's impossible to uniformly decide how process an invoice based on the invoice alone (e.g. is this deductible? is this even a business expense at all? which ledger should this go in? etc).
