Your best option (that comes to mind for me at least) would probably to use this CSV as a lookup. Past 8000 search terms or so you're not getting a performance boost out of adding more terms anyway (and there's even a hard limit of 10500 results that you can emit from a subsearch), so you might as well run a query against all data and then filter it using your lookup.
Your lookup would be something like:
Session_ID,exists
000002b89784b98e91bd,1
1c1b68e349f3b98f3570,1
1c1b68e349f3b98f4d3f,1
And then your search would look something like this:
sourcetype=j_s_i | lookup session_ids Session_ID OUTPUT exists | search exists=1 | stats count by Status
