Liverpool already turned down a chance to get a much bigger gap, so they can't really afford to lose to Villa at this point, even a tie wouldn't be really ideal for them. They had a great season so far and I am pretty sure that we are going to end up with a much better situation here and could do a lot better on the long run as well. This is why I can see how Liverpool will put everything they have into this game and get a win.
Luckily, Liverpool finished in top 8 for UCL so they could put this game here, if Liverpool was somewhere between 9-24 they would have UCL game instead, with this game they are going to be getting ahead again so they are going to need that extra game and extra points in this case as well, would benefit them.
Liverpool really shouldn't be able to lose to Aston Villa if they want to become champions this season because of course to win the title it would be better to have a big difference in points with the other teams. After Liverpool beat Wolves in their last match, of course I am also sure that Liverpool will win again at Villa Park because I still believe in the strength of Mo Salah and the others who will definitely be able to score a goal against Aston Villa which will end in victory for Liverpool.
This season, Liverpool is considered a good club with good performance and it would certainly be a shame if Liverpool's performance had to decline at this time. but I am also the same as you because I also believe that Liverpool will use all their strength so they can win the match later. Yes, Liverpool are very lucky because they finished with a good ranking in the UCL, so now Liverpool will definitely enjoy this match more in the EPL, which is of course different from other teams, which of course have a busy match schedule because they are busy fighting for the top 16 in the Champions League. It looks like in the Liverpool vs Aston Villa match I will bet on Liverpool winning.
