Why assume that OCR does not involve context? OCR systems regularly use context. It doesnt require an LLM for a machine reading medical forms to generate and use a list of the hundred most common drugs appearing in a paticular place on a specific form. And an OCR reading envelopes can be directed to prefer numbers or letters depending on what it expects.

Even if LLMs can push a 99.9% accuracy to 99.99, at least an OCR-based system can be audited. Ask an OCR vendor why the machine confused "Vancouver WA" and "Vancouver CA" and one can get a solid answer based in repeated testing. Ask an LLM vendor why and, at best, you'll get a shrug and some line citing how much better they were in all the other situations.
