there just isn't enough light for thriving tomato plants indoors.
The figure of merit for light intensity is PAR (photsynthetically-active radiation)
The absolute top-of-the-line money-is-no-object LED for indoor cannabis growers is the Fluence Spydr:

A single 4' x 4' LED fixture costs $1,400 and claims 1,060 µmol/m2/s PAR output
for comparison, the free nuclear reactor in the sky provides 2,000 µmol/m2/s PAR on a cloudy winter day, and 3,000 PAR on a sunny summer day

So spending an ungodly sum on money on LED lights will get you at best 30-50% of the light that your outdoor tomatoes got in the summer
and cheaper grow lights will provide even less
