Obviously not familiar with current matters at training pitch, but regarding other circumstances I would go with:
Ortega: its a cup and he more than deserved these games,
Lewis/Cancelo: its a cup and Walker played much enough at world cup, evidently was rushed back from injury, better to be catious with him. On the other hand Cancelo play similar minutes to Walker, but was dropped at some point and needs to regain his confidence, especially since recent games for City werent his best,
Akanji: simply because played one game less than Stones and Dias during WC,
Laporte: simply because played one game less than Stones and Dias during WC,
Gomez/Cancelo: its a cup, but above-mentioned argument for Cancelo stays
Philips: its a cup, he needs to get minutes, maybe Rodri should rest a bit more, on the other hand its against generally well rested LFC after all, so would not be surprised with Rodri,
Gundogan: he needs to play to regain confidence after early exit from WC,
De Bruyne: I am sure hes going to play, similar case to Gundogan,
Mahrez, Haaland: even more sure they re going to play for obvious reasons,
Last spot looks like between Grealish/Silva/Palmer and I would go with Grealish - Silva played much enough during WC to prolonge softly his return and Palmer was not at his best against Girona, so against LFC it shall prevailed a spot for Jack.
