Same as Bitcoin: total fee = vbytes × fee rate (litoshi/vB). Vbytes count witness data at a 4× discount, so SegWit and Taproot transactions pay less than legacy ones for the same logical operation.
Litecoin produces blocks roughly 4× faster than Bitcoin (every 2.5 minutes vs 10) and has lower demand pressure. The mempool clears more often, so fee rates settle near the minimum almost continuously.
Yes — Litecoin inherits Bitcoin's SegWit and script structure, so a P2WPKH 1-input/2-output transaction is the same ~141 vbytes on both chains.
