Need review on ai extraction layer

I'm building a document parsing platform for the insurance industry. So, brokers upload pdfs, and an ai pipeline extracts data from them.

preprocessing → parsing → extraction, via RabbitMQ, Python/FastAPI backend.

I need an experienced opinion specifically on the AI extraction layer - is our pipeline architecture right. More details in the images attached.

I'm especially interested in hearing from anyone who's worked on document intelligence systems where extraction accuracy matters more.
