Today's match is Fulham's home match. Still, I see no reason to think Fulham are favourites. This group is not very strong. They also lost against Chelsea in their last Premier League match. Also, if Liverpool draw today's match, they can qualify for the next round. So the possibility of Chelsea vs Liverpool final is more likely.
But in my opinion, the match at Fulham's home will not be burdensome for Liverpool after all, this is not a busy match so the players can be excellent in this match, to dominate the game, it is clear that Liverpool will master it, it is likely to decline all of its main squad.
A draw is enough for Liverpool, but if they think they can win then it will be much better, I'm not sure Fulham will continue to attack maybe the opposite where Fulham can be a defensive game in this match.
Looking at the betting market, the bookies offer odds on Liverpool which are quite large @1.84 this is still worth betting on in my opinion Liverpool will pursue the EFL trophy and finish it later in the final with Chelsea.
As only a draw is enough for Liverpool, I see Fulham's chances of winning very low. Because Liverpool's defense is very strong. It would not be wrong to say that Liverpool have the strongest defense in the Premier League. The team conceded only 18 goals in 21 matches. On the other hand, the opponent Fulham is not strong. Fulham's players will not be able to break Liverpool's defense if Liverpool plays defensively. So my guess is that the match will either draw 1-1, or Liverpool will win 2-0 or 2-1. I don't even think Liverpool will win by a big margin.
