Liverpool is not worried about the EPL Cup at all, we can understand it by looking at their position. Liverpool is currently in a good position, but all other teams will still have to compete extensively to occupy their position, which may not be possible for them to surpass. But their loss in the FA Cup does not seem so weak to them, besides, Liverpool is currently in the best position in the UCL. However, we can ensure that maybe Liverpool will have to lose any trophy, UCL, FA Cup, these two trophies may not be in their hands. But we can give them assurance for the EPL and if Liverpool can manage their game in such a way and continue to move forward correctly, then they will be champions. Since Liverpool is currently in the best position in the UCL, it is not sure how long their position will last, but they are guaranteed to be champions in the Premier League.
IMO, it would be better if Liverpool lost the FA Cup title than losing the UCL title after getting the best position at the moment. I feel that Liverpool this season is really very consistent and has a comfortable position in every competition. But somehow Liverpool must give up one of the competitions so as not to lose their best performance. Because if Liverpool continues to pursue the title in all competitions, surely the players' physical condition will be exhausted and their performance will start to decline. So it would be better for Liverpool to start prioritizing several competitions to become the main goal.
