As long as you dodge the skillshot it can't hurt you.
Nidalee can do practically the same thing with her spear, on a much lower CD, excluding the inability to hit multiple people with the spear. A max range Nidalee spear, going off of its base 230 damage X 2.5 for max range multiplier, does 575 damage. In addition, at max range, its AP damage ratio goes up to about a 1.6, more than double the .75 ratio on Lux's ult. One lucky nidalee spear can out damage lux's ult on one person. In addition, Nidalee's spear has a 6 second CD compared to Lux's 40 second CD, this is if no CDR is built, which means in the amount of time that it takes for Lux's ult to come off CD after being fired, Nidalee has thrown about 6 spears in that time. 3450 damage if she lands them all. Max base damage on Lux's ult is 2500, IF she gets lucky enough to hit everyone on the enemy team. If Lux's misses she doesn't have it for 40 seconds, if Nidalee misses, no problem, just pounce away if they get too close, and throw a spear again in 6 seconds.
Now lets give them each a Rabadon's Deathcap. 150 AP about. Lux gets 112 bonus damage. Nidalee gets about 240 bonus damage per spear. Lux will do 612 damage per person hit, Nidalee at max range will do about 815 damage. Now Lux HAS to land hers on as much people as possible, a miss means its gone for the next 40 seconds. While Nidalee can just keep chucking spears because 6 second CD, missing won't hurt her at all pretty much..
First of all, Nidalee's spear is slow travelling, has a small hitbox, and as you pointed out, is single-target.
Secondly, AP Nidalee is not a particularly valid build in the first place, due to her spears being the only real, sustained use she has, and that only being good while maintaining distance.
She gives up any sort of decent dueling or sustained damage by building AP.
Now, looking at Lux, she has 3 other abilities, one is a decent multi-target shield, and the other two deal decent damage and offer good CC at long range.
Neither of these champions are useful in extended teamfights, but Lux's CC and shield make her vastly superior in almost every situation.
Now, looking at Lux's Ultimate itself, while it can be pretty easy to dodge, its width is quite large and the hitbox is a little wonky.
Often-times, players will think they've dodged it but still be hit by the edge of the hitbox (if not the animation).
Now, this is a psychological thing, as several ultimates that are similar (e.g. Ezreal's) are the exact opposite, where standing on the edge often results in a player taking no damage.
Regardless, it needs to be taken into consideration, as perfect reaction speeds and recollection are unlikely "in the heat of battle".
Also, I would like to point out that Lux's ultimate will not be on a 40 second cooldown unless the person playing her has no idea what they're doing.
That sort of thing should be included in the comparison.
