Create io.datasette.llm in Application Support on install

[mikesten]

Small on here... I think you need to create the io.datasette.llm directory on install (or check before logging).

I've tried installing llm via brew and pip, and both get this error from the sqlite logging after successfully running a command:

$ llm 'hello world'

I create io.datasette.llm myself manually and everything's fine:

~/Library/Application Support $ mkdir io.datasette.llm
~/Library/Application Support $ llm 'hello world'

Hah yeah this is a bug - that folder is meant to be created automatically but clearly there's a case where it isn't.
