tl;dr: magic damage and true damage do not interact with lifesteal, only the physical damage of the auto itself (blade of the ruined king passive, spellblade, champion abilities increasing or adding physical damage to the autoattack)

No, you're wrong, because if you had actually read the "Life Steal" page, you would know that lifesteal doesn't work with true damage, it only works with physical or magic damage originating from the attack itself (magic namely in the case of corki, whose 20/80% physical/magic damage autoattacks will apply lifesteal on the magic damage portion), and to physical spellblade effects (lich bane does not proc lifesteal, trinity force and iceborn gauntlet do). life steal does not interact with any true damage effects, just like master yi's E active, (the lifesteal page specifically states the lack of interaction with true damage)

essentially, before damage reduction, a champion with, hypothetically, 50 base ad and 50 bonus ad (100 total ad, let's ignore the bonus ad from conqueror to simplify the math), 10% lifesteal, conqueror keystone, and trinity force would deal 100 (total ad) + 100 (200% base ad spellblade proc from trinity force) = 200 damage on an AA, and would heal for 20 hp, but after conqueror true damage conversion, they would deal 160 physical damage and 40 true damage on AA with spellblade proc, but would only heal for 16 hp

in the case of a lichbane proc, with let's say 100 ap, autoattacking a champion while having 50 base ad, 50 bonus ad, 10% lifesteal, and 100 ap, would deal 100 physical damage, 37.5(base ad spellblade scaling) + 50 (ap scaling) magic damage, totaling to 100 physical damage, 87.5 magic damage, and only healing for 10 hp from the physical damage and lifesteal not applying to lich bane proc, and after conqueror damage conversion, you would deal 80 physical damage, 70 magic damage, and 37.5 true damage, but only heal 8 hp from the physical damage with 10% lifesteal
