Retrieve Token Usage outside of ell-studio

[schenktobi]

First, thanks for this library, it is really helpful. I didn't find anything inside the docs, so I'm asking this way.

Does anyone know of a way to retrieve the token usage of the made llm_call, when using @ell.complex outside of ell-studio

I know I can look at the token usage in the ell-studio, but we log our llm calls inside our db and estimate costs when testing new features that way. Any help would be greatly appreciated.

Thanks in advance and sorry if i oversaw something
