Hello Tanya,
Since you've LAG/Port-Channel configure on physical switch side, you will need to use Route Based on IP Hash, check the NIC Teaming Requirements: VMware KB: Host requirements for link aggregation for ESXi and ESX
Anyway I will recommend you read the following blog post and decide if change your design to Route Based on Physical NIC Load, but take in mind that if you choose change to LBT, you will need remove the LAG/Port-Channel on physical switches.
