PendleLPOracle uses Chainlink to get the price of Pendles underlying asset in ETH; this is done using _fetchAndValidate. That function uses answeredInRound, which is deprecated according to Chainlink docs.
This results in invalid/wrong prices from Chainlink.
Remove the usage of answeredInRound in PendleLPOracle::_fetchAndValidate.
