##No, Leomund's Tiny Hut is made of magical force which blocks passage in the Ethereal Plane

In the description of the Border Ethereal on DMG p. 48:

A traveler on the Ethereal Plane is invisible and utterly silent to someone on the overlapped plane, and solid objects on the overlapped plane don’t hamper the movement of a creature in the Border Ethereal. The exceptions are certain magical effects (including anything made of magical force) and living beings.

So, objects made of magical force will block passage on the Ethereal Plane just as they do on the Material plane.

The description for Leomund's Tiny Hut (PHB, p. 255) says:

A 10-foot radius immobile dome of force springs into existence around and above you and remains stationary for the duration.

So, since Leomund's Tiny Hut is a dome of magical force, it should protect your party from intruders on the Ethereal Plane as well.
