Final answer:
Lisa's lack of awareness of Pizmo's knowledge of her identity as a corporate spy is evident through her overconfident behaviour and there is no text evidence of her knowledge of being exposed.
Step-by-step explanation:
Based on the provided text, Lisa does not appear to be aware that Pizmo has realized she is a corporate spy. Pizmo's decision to call his business partner and reveal Lisa's true identity is a pivotal moment indicating her cover has been blown.
However, there is no direct evidence within the text that suggests Lisa is aware of Pizmo's discovery or his subsequent actions. The text presents Lisa as overconfident in her cover, bragging about her undercover cases and her hobby of visiting bars, which implies a lack of awareness about her compromised position.
