"When I use True Strike with a Cleave weapon and hit, how do I use to resolve the additional attack from Cleave?"
(1) Cleave is a weapon mastery property. Only Barbarians, Fighters, Paladins, Rangers, and Rogues can gain and take advantage of weapon masteries.
(2) every one of those classes get ExtraAttack except Rogue. And TrueStrike doesnt work with ExtraAttack.
Therefore this is a very niche situation as most of these classes will be getting ExtraAttack at which point using TrueStrike will be a downgrade. But for those niche cases, where someone has learned thr weapon mastery property, does not yet havr ExtraAttack, and has a better spellcastung ability than strength, then TrueStrike would work with Cleave weapon mastery.
But cleave says if you hit with a melee attack (which woukd be truestrike), you can make a second melee attack, that does weapon damage only. This would be outside the scope of TrueStrike, so you would havr to use Strength tohit on that cleave attavk
"Eldritch Knight Fighter can use True Strike or any other Wizard Cantrip they know instead of one attack during an Attack action."
So you dont need the feat also, you cant swap an attack for a cantrip until level 7, and you can only do it for 1 attack, not the extra attack, and by level 11, youve got 3 attacks, and only one can be truestrike.the other 2 (and the cleave attack) will have to use dex or str.
If you want to use spellcasting ability for melee attacks, prob goijg to be more powerful to do a pact of the blade+paladin. If are willing to use a quarterstaff, take thr Guide background, pick up shillelagh using INT as your spellcasting ability, and then max your int, go all eldrutxh knight, and just cast shillelagh first turn, and whack away.
Shillelagh from the origin feat, letting you choose your spellcasting ability, leads to some really crazy op builds.
RAW, it is an option regardless of your opinion on the matter. Every class has access to the feat. If you want to make a Warlock with Pact of the Blade and Cleave Weapon Mastery, go nuts. It may be more useful for College of Valor Bards that most other non-martials.

You don't need the Feat as an Eldritch Knight. You can swap for a Cantrip once per attack action. That is what I said, "instead of one attack". True Strike will use Intelligence in most cases with an Eldritch Knight. The other attacks will have to use Strength unless you found a Finesse Weapon that also has the Cleave Weapon Mastery. Alternatively, an Eldritch Knight that dipped into Warlock for Pact of the Blade could be leaning heavily into Charisma (and multiclass cantrips are weird). There may be reasons to sacrifice the bonus to hit in order to deal radiant damage (including up to an extra 3D6 Radiant Damage), if you're looking to Cleave, you probably are fighting multiple, hopefully lower-level enemies and their AC drop might match your hit chance drop.

Shillelagh can't be cast on weapons with the Cleave Weapon Mastery, which is what we are discussing here. True Strike and Cleave. If Shillelagh could be cast on the haft of a Halberd for shenanigans, Shillelagh would be relevant here. Maybe in the future.

None of that was the question. However, both are wrong.
(1) Anyone can take the Weapon Master feat to get access to one weapon mastery which they can change out on a long rest as normal.
(2) An Eldritch Knight Fighter can use True Strike or any other Wizard Cantrip they know instead of one attack during an Attack action.

Not me. Not worth it never seen anyone do it.
