Those liches, vampires and other undead under his command increase his power base, not individal power. Oh, and Larloch don't have complete spell imunity, his spell imunity is similar to the one possesed by Chosen of Mystra.

As for wizards more powerfull that Larloch [those who will beat him in one-on-one duel] there are:
Telamont Tanthul - ruler of City of Shade and 35th level Wizard
Oysar Shoon VII - formerly 36th level Wizard and demi-lich, currenly living inside a body of a young elven maiden (who herself was 3rd level Wizard and demi-lich [don't ask, it's a long story]) and who still have access to all of his previous knowledge
Currently unnamed members of Twisted Rune [their levels and powers are unknown but since Shoon think he's still not powerfull enough to fight them...]
Queen Amlauril of Evermeet - she's was somewhere between 25th and 30th level wizard before dying, but since then she was resurected by direct intervention from Correlon Larethian and made into Chosen of the Seldarine [the entire elven pantheon, as opposed to being Chosen of a single deity like Elminster, Cadderly or Fzoul Chembryl are] so her current power level can only be guessed.
Shrinshee - moon elven wizard, formerly baelnorn restored to life [and youth] by Mystra and then made Chosen [of Mystra] who was 30th level when Myth Drannor fell. It's believed that she spend a lot of time since in Arvandor, keeping guard over Crownblade.

But all of those guys can hide in fear from one that can take them all [probably even at the same time]: the so-called "Father of Netheril" - Iolaum

Iolaum was oldest and most powerfull Wizard even during the time of Netheril [not suprising considering he's at least 1.000 years older than all others mentioned before, and that he was 300 years older then Netheril itself] and has since fall of Netheril survived as a Elder brain [as the ones that are at the center of each Illithid community] Lich with 41 wizard levels.
It is also believed that Iolaum was responsible for creation of first Alhoon [Illithid lich] from his Illithid students (he used arcane ritual to fuse brains of those students into a elder brain that he than took full control of, destroying their individual wills in the process).
Today he is known as Oracle of Ellyn'taal [and is not suspected to be Iolaum], and the few who ventured into his halls gained pieces of arcane knowledge dating back to formation of Netheril, but at a terible price - voluntary loosing pieces of aplicants sanity [represented with permanent loss of 1d4 points of Wisdom] or piece of arcane knowledge possesd by aplicant [complete permanent loss of a epic spell known by caster]

Among honorable mention category should be listed:
Lady Saharel, another survivor of Netheril, formerly 30th level wizard who after ToT survives as CG ghost [and who is deply inlove with Elminster]
Tabra, last human apprentice of Iolaum who was 23rd level wizard at the time her master become elder brain some 1.500 years ago, and who is still alive today (possibly the only survivor of Netheril still living who is not a Lich, Shade or some other form of undead) due to repeated uses of Iolaum's longevity spell.

Ehh... where did you get your information on Larloch? Last I heard was he's a level 46 Demi-Lich. I think Wizard 36/Archmage 5/Netherese Arcanist 5, if I'm not mistaken.
