Well looks like you are down to Tom's suggestion of creating a test case. Given that it seems confined to the jsonb field and corresponding index, I would think that is all that is needed for the test case. Start with some smaller subset, say 10,000 rows and work up till you start seeing an issue.
This will take quite some work, and I wouldn’t attempt it with less than 5M rows to load.
From this post:

You started seeing longer times by the time you got to 500,000 rows and
then it fell off by 1.1 million.
Creating the data:
CREATE TABLE AS gin_test SELECT traits FROM eis_entity LIMIT 1000000;
Then:
pg_dump -t gin_test
