That is a gigantic offset for a modern opamp.

It's noisy too.

RRIO, low offset, "high voltage", cheap, pick three I guess

There are lots of different "modern" ops amps, optimised for lots of
different jobs. The OPA4991 has lots of unique advantages, but low
offset and low noise aren't any of them.
