The whole encounter feels like a rough draft. There is a good encounter in there but it just needs a few things.
One of which [Tuco] just alluded to, there needs to be more roadblocks between you and that encounter. Because Lae'zel to Druid Grove, to Blighted Village (since you have to pass through) to Gith is a bad idea. You will be level 3 if you are lucky and unless you make the dialogue checks - you are dead.
Soft roadblocks is one of the better ways to go about it. Currently, there's nothing directly between the Blighted Village (level ~3) and the Gith. The burning village is almost in the way, but it doesn't actually grant much exp.
The map/encounters should be rearranged so that the gnoll and paladin/tiefling encounters are on the way to the Gith, with the encounter immediately before the Gith being a difficult but doable fight for level 4 characters. Alternatively, an additional such encounter could be created on the path from blighted village to the Gith. Players would thus be warned that the Gith encounter, if it leads to combat, will be even harder for level 4 characters.
Importantly, players are not
prevented from reaching the Gith as they can either beat or sneak past ^ encounters. It's just made more difficult for lower-level parties to accidentally reach them.
