LTSpice Sallen-Key Filter
First off. If you want the calculations to match up, then you need to use an ideal amplifier. The ideal amplifier in LT spice is found in the opamps folder, you need to add the spice line 

.lib opamp.sub 


for lt spice to find the library for the part. 

Then set the ideal opamp's open loop gain to something insanely high like

Aol=10000000K

and the gain bandwidth product to something insanely fast like:

GBW=10000Meg

The reason you need to use an ideal opamp is because filter tools assume that there are no losses and ideal opamps (unless they have a section to change the op amp). The GBWP and open loop gain create a pole, which hampers the opamp's ability to function at high frequencies



Secondly, your not using the same numbers in each of the tools:



and here are my numbers... 



it looks like the graphs match up to me. But only up until about 100kHz where the amplifier starts to make a difference again. 

It would be extremely hard to build a filter with the values you have chosen for components. Traces and wires have miliohms of resistance, so choose values that are not in that range, otherwise you wouldn't be able to bulid this circuit. Caps in the farad range are also undesirable because they are bulky and expensive.
