Do radiator fluid leak from oil sending unit?

No. Coolant should not leak from the oil sending unit. the unit's purpose is to send a pressure reading to a guage or, in case of a warning light, turn it on in the event of an unsafe drop in oil pressure. no anti-freeze coolant should come from this unit. if there is, you are most likely looking at the temperature switch or sending unit and not the oil sending unit. however.. if there is a mixture of coolant and oil comming from it that has a milky look to it then you have coolant seeping into your oil which indicates a blown head gasket, cracked or warped head, or a cracked block.
