Its for strength and weight reduction. If it was not made this way the connecting rod would weigh twice as much . Less weight in the internal rotating mass of the engine is good.

You seem to know about I-sections already so the answer should be obvious. It is for strength primarily, and then for weight reduction.
The I-section would not be a useful design had it not been manufactured the correct way i.e. by drop forging. This process gives it the strength it needs. Though some light engines are known to have pressure die cast magnesium connecting rods.

What he said, same as an steel I-beam in a bridge, or a wood stringer I-beam made for houses.
