Yes, the LEA-*T's have a TCXO.
I'd expect less jitter in the 1PPS if the oscillator is more stable.
A TCXO has usually something in the range of 10-100ppb/°C temperature
coefficients, while from a OCXO you can expect <10ppb over its whole
temperature range (usually somewhere from 0 to 50°C), ie getting
a temperature coefficient that is in the range of 10 to 100 times better.
