MOST of the time, it is worth to just block the first 3 hits of F434 and IMMEDIATELLY either microduck into a combo, or just duck and poke. That way, you avoid liu kang doing F43 into Motaro (if you are fast enough, you will interrupt it and fully punish it), you will also avoid F43 staggers into throw. You WILL be caught in the last kick if he decides to do the 4 hit string fully - but most decent lius wont commit to that often, as flawless blocking the last hit opens him up for a full punish as well. You can ALSO do an armored move after F43 and avoid both motaro and lao's hat.
However, this is all more easily said than done.
