Just a passing FYI that there is no admin option on the llamaserver to switch either the scoregraphs or the llamascores on for the game once the game has started. Whether the llamascores appear during the game seems to be directly linked to the pre-game 'scoregraphs on Yes/No' option. (at least as far as the admin is concerned and can control)
There have been times when the llamascores suddenly appeared mid-game by accident (in games with scoregraphs off). But each time this happened it was associated with a bug in the llamaserver (due to how it used to handle Dominion patches IIRC). Llamabeast possibly could switch the llamascores on for you, but I doubt he'd do it if it risked messing with the operating code (just in case it affected other games by accident)
If you desperately want to know what the current graphs look like, then each player can go around their empire and do a lot of counting
As every graph criteria can be worked out by hand if need be. (and if you're insanely bored)
