Should I use a voltage divider circuit with two resistors to drop the analog 0 to 5V signal from a DFrobot SEN0159 CO2 sensor that I intend to connect to an analog pin on my brand spanking new MKR1000 board? I ordered a four channel bi-directional level shifter for the I2C bus connection to the LCD, but it's my understanding these are for digital signals, not analog. Or, am I mistaken?

Yes. Use the voltage divider idea.
