'NaN' and 'Infinity' getting casted as Double it seems. It goes through double datatype.

I don't think so. Please try CREATE TABLE test_nan WITH (format = 'json') AS SELECT real 'NaN' a;.

fixes #20395 #20395
This pr will fix inserting NaN and Infinity into table as Json Format.
In hive, if we insert NaN or Infinity in json format table, it would store that as NULL, which readable from Trino. We can go that path also if we want to create table to be successful.
