We adopt the Hartree-Fock (HF) method and the nucleon-Lambda Tamm-Dancoff Approximation (N Lambda TDA) to study the energy spectra of selected medium mass hypernuclei composed of a Lambda hyperon bound to an even-even and odd-even nuclear cores. Our calculations are carried out using the Y N LO potential plus the chiral potential NNLOsat, which includes explicitly the 3-body NNN force. This component, while improving the r.m.s. radii of the nuclear cores and the relative distances between levels or group of levels of the hypernuclear spectra, strongly reduces the binding energies indicating that the inclusion of more complex configurations is badly needed.
