Shouldn't the Amount Financed on the early TIL be the same as the amount shown on the GFE under "Your initial loan amount is"? (assuming they were produced the same day)

If I understand your question correctly, then no, these two amounts would not match. For TILA purposes, the amount financed is the Note amount, less the prepaid finance charges. The "initial loan amount" on the GFE would be the same as Note amount.
