The proto Sun would still have been pretty hot, from gravitational
energy from all that gas and stuff falling in on it. Also the proto
Sun probably started fusion when it had 10% of its current mass
accumulated already.

The Moon probably wasn't around when the Sun fired up. It
formed later after the Earth got nailed by that Mars sized
planet they think formed at L4 or L5 of Earth's orbit.

It isn't unlikely that the collision occurred at a time when both
objects were still fairly amorphous, possibly well before solar
ignition.
