Is this needed? I think a max value will be assigned in args.ToMessage.

Hm but no default is set in args.toTransaction. So I guess its fine

Yeah. But setDefaults is called before args.ToMessage in some functions, if we want to bypass DoEstimateGas to gain some performance, then need to add a bypass param in setDefaults.

// but need to ensure that gas is sufficient.
if infiniteGas {
tmp := hexutil.Uint64(math.MaxUint64 / 2)
args.Gas = &tmp

This will overwrite any user-provided gas limit. Please put it under the if args.Gas == nil check. Also IMO infiniteGas is not a great name. Maybe skipGasEstimation? The other point is that we should set ideally to the RPC gas cap (see ToMessage).

Make sense, the comments are addressed in ee59f15.
And TestGethClient/TestAccessList is passed now.
