  It has been suggested that relativistic jets might have been commonly formed
in tidal disruption events (TDEs), but those with relatively weak power could
be choked by the surrounding envelope. The discovery of high-energy neutrinos
possibly associated with some normal TDEs may support this picture in the
hypothesis that the neutrinos are produced by choked jets. Recently, it was
noted that disrupted stars generally have misaligned orbits with respect to the
supermassive black hole spin axis and highly misaligned precessing jets are
more likely to be choked. Here we revisit the jet break-out condition for
misaligned precessing jets by considering the jet could be collimated by the
cocoon pressure while propagating in the disk wind envelope. The jet head
opening angle decreases as the jet propagates in the envelope, but the minimum
power of a successful jet remains unchanged in terms of the physical jet power.
We further calculate the neutrino flux from choked precessing jets, assuming
that the cocoon energy does not exceed the kinetic energy of the disk wind. We
find that neutrino flux from highly misaligned choked jets is sufficient to
explain the neutrinos from AT2019aalc, while it is marginal to explain the
neutrinos from AT2019dsg and AT2019fdr. The latter could be produced by weakly
misaligned choked jets, since the duty cycle that the jet sweeps across
increases as the misaligned angle decreases. We also show that the population
of choked TDE jets could contribute to ~10% of the observed diffuse neutrino
flux measured by IceCube.
