This is a universal problem in football - not just Dyche. The likelihood of a team in the bottom half (and generally, but lower for worse teams than top teams) of the table coming back from conceding a goal first is very low.
Herein lies the very essence of how a manager must constantly find equilibrium between balance and imbalance, and how the team chooses tactics.
Liverpool can e.g. in most matches stand 1 on 1 against the attacking players, and usually do this without any particular risk because they are better individual players. Isolate Tarkowski against Haaland (and quite a few PL attackers), and you have the definition of madness. Put DCL up in one on one situations against PL CB, how many does he win? We can do this for all players.
Different models can then be used to compensate. Then you have to ask yourself, what are Everton's strengths? We don't have very many technical and creative players, do we have any? We also don't have many players with great pace. However, what we have is a bunch of players who have great work capacity, and a squad that has the highest average height in the PL.
Looking at the strengths and weaknesses, Dyche's style is not very illogical. Defensively solid, crosses in the box, transitions and set pieces. People here argue for the illogical. To force together pieces that do not fit.
